Move the slope duration and threshold update in a separate function to
reduce code duplicate between chip init and motion interrupt setup.

Also move the slope update code from the interrupt setup function to
the trigger set state function so that we can later refactor the
interrupt code.

Subject: iio: bmc150: refactor interrupt enabling

This patch combines the any motion and new data interrupts function
into a single, generic, interrupt enable function. On top of this, we
can later refactor triggers to make it easier to add new triggers.

Subject: iio: bmc150: exit early if event / trigger state is not changed

Previous of this patch the check was only done if we enabled the event
and it was already enabled. We can do the same if the event is
disabled and we want to disable it.

The patch also adds the same check on the trigger code.

Subject: iio: Export userspace IIO headers

After UAPI header file split [1] all user-kernel interfaces were
placed under include/uapi/.

This patch moves IIO user specific API from:
	* include/linux/iio/events.h => include/uapi/linux/iio/events.h
	* include/linux/types.h => include/uapi/linux/types.h

Now there is no need for nasty tricks to compile userspace programs
(e.g iio_event_monitor). Just installing the kernel headers with
make headers_install command does the job.

Change struct iio_prtc_trigger_info frequency
type from int to unsigned int.
Since it is always treated as such in the driver
so they type should probably reflect this.

Subject: iio: improve usage of gpiod API

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for
outputs.

Subject: staging: emxx_udc: Replace GFP_KERNEL with GFP_ATOMIC

To avoid deadlock, do not call blocking functions with spinlocks held.

Replace GFP_KERNEL with GFP_ATOMIC, as the latter will fail if the pile
doesn't have enough free pages but will not sleep and hence deadlock can
be avoided.

Found by Coccinelle.

Subject: iio: imu: inv_mpu6050: Create mux clients for ACPI

This is a follow up patches after adding i2c mux adapter for bypass
mode. Potentially many different types of sensor can be attached to
INVMPU6XXX device, which can be connected to main cpu i2c bus in
bypass mode.
Why do we need this?
The system ACPI table entry will consist of only one device for
INV6XXX, assuming that this driver will handle all connected sensors.
That is not true for the Linux driver. There are bunch of IIO drivers
for each sensors, hence we created a mux on this device. So to load
these additional drivers, we need to create i2c devices for them
in this driver using this mux adapter.

There are multiple options:
1. Use the auto detect feature, this needs a new i2c class for the
adapter as the existing HWMON class is not acceptable. Also the
autodetect has overhead of executing detect method for each
matching class of adapters.
This is a simple implementation. This option was previously submitted
with not a happy feedback.

2. Option is use ACPI magic and parse the configuration data. What
we need to create a i2c device at a minimum is address and a name.
Address can be obtained for secondary device in more or less in a
standard way from using _CRS element. But there is no name. To get
name we need to process proprietary vendor data. Not having name is
not fun, as you have to create device using the device name of
INVN6XXXX, respecting driver duplicate name space restriction.
Also each client driver needs to have this name in the id table.
Since multiple driver can be loaded, the driver should be able to
detect its presence and gracefully exit for the other client driver
to take it over.
So we use two step process:
- Use DMI to id platform and parse propritery data. This is not uncommon
for many x86 platform specific driver. We will get both name and address.
The change created necessary infrastructure to add more properitery vendor
data parsing.
- If DMI match fails, then create device on INV6XXX-client (we can't
create with same name as INV6XXX as it will cause duplicate name and driver
model will reject.) With this each client sensor driver which needs to get
attached via INV6XXXX, need this name in the id table and detect the
physical presence of sensor in probe and exit if not found.

Subject: Staging: lustre: lnet: klnds: o2iblnd: Remove intialization of static
 to 0

ERROR: do not initialise statics to 0 or NULL
checkpatch.pl error in o2iblnd_modparams.c
initial value unassigned static variables are automatically set to zero.
so it is unnecessary to assign the initial value to zero

Subject: Staging: vt6656: replace memcpy() by ether_addr_copy() using
 coccinelle and pack variable

This patch focuses on fixing the following warning generated
by checkpatch.pl for the file rxtx.c

Prefer ether_addr_copy() over memcpy() if the Ethernet addresses
are __aligned(2)

@@ expression e1, e2; @@

- memcpy(e1, e2, ETH_ALEN);
+ ether_addr_copy(e1, e2);

According to ether_addr_copy() description and functionality,
all Ethernet addresses should align to the u16 datatype.
The changes were applied using the following coccinelle rule:

Here is the output of pahole for the relevant datastructures:

Subject: Staging: rtl8188eu: Use put_unaligned_le16

Using byte ordering functions and then memcpy() is risky and
prone to hide errors which are hard to track down. So, this
patch introduces the use of function put_unaligned_le16 which
makes the code clear. Here, use of variable tim_bitmap_le
and variable itself is removed. Also, to be compatible with the
changes header file is added too.

Coccinelle is used to do this change and semantic patch used for
this is as follows:

expression y,e;

Subject: Staging: rtl8188eu: Changed array and loop construct

This function only required the array from the 14th element
onwards. Therefore, the array size is reduced and the loop
counter is modified so as to start from 0.
Also, the assignment of variable place is redundant as it is
initialized again in the loop.

Subject: Staging: rtl8188eu: Combine two loops to increase readability

The first loop assigns values to ofdm_index array and the
second checks for boundary conditions. They are combined and
a comment is added to increase clarity.

Subject: Staging: rtl8723au: Use put_unaligned_le16

Using byte ordering functions and then memcpy() is risky and
prone to hide errors which are hard to track down. So, this
patch introduces the use of function put_unaligned_le16 which
makes the code clear. Here, use of variable tim_bitmap_le
and variable itself is removed. Also, to be compatible with the
changes header file is added too.

Coccinelle is used to do this change and semantic patch used for
this is as follows:

@a@
typedef __le16;
__le16 e16;
identifier tmp;
expression ptr;
expression y,e;
type T;
@@

- tmp = cpu_to_le16(y);

<+... when != tmp
(
- memcpy(ptr, (T)&tmp, \(2\|sizeof(__le16)\|sizeof(e16)\));
+ put_unaligned_le16(y,ptr);
|
- memcpy(ptr, (T)&tmp, ...);
+ put_unaligned_le16(y,ptr);
)
...+>
? tmp = e

@@ type T; identifier a.tmp; @@

Subject: staging: fbtft: fix spacing errors

This patch fixes the following checkpatch.pl errors:

space required after that ','
spaces required around that '='

Given that the addition of spaces triggered the line over 80 characters
warning, some lines were divided into two.

Subject: Staging: rtl8712: Use mod_timer

This patch introduces the use of API function mod_timer
instead of driver specific function as it is a more
efficient and standard way to update the expire field of
an active timer.

Subject: Staging: slicoss: Join split string.

This patch fixes warning issue by checkpatch.pl by joining the split string.
And also creates new warning that line exceeds 80 characters. In this case
this is more beneficial because of possibility to grep the string.

Subject: staging: rtl8723au: rewrite the right hand side of an assignment

This patch rewrites the right hand side of an assignment for
expressions of the form:
a = (a <op> b);
to be:
a <op>= b;
where <op> = << | >>.

This issue was detected and resolved using the following
coccinelle script:

-i = (i >> e);
+i >>= e;

@@
identifier i;
expression e;

For dynamic debugging netdev_dbg(), dev_dbg() or  pr_debug() macro is
preferred over printk(), which is the raw way to print something.
Network system has it's own printk format, netdev_dbg, but in this case
function's argument list has no  pointer to a struct netdevice so
pr_debug is used instead.

Subject: staging: unisys: remove unneeded functions

these functions are not being used anywhere.so we can remove them.
has been verified by "git grep" that they are not being referenced
anywhere also has been build tested.

Subject: unisys: replace kthread_create and wake_up_process with kthread_run

kthread_run calls kthread_create and if the thread is created
it then calls wake_up_process on the corresponding returned
task struct. So the code can be simplified by calling just
kthread_run.

Subject: unisys: use simpler kthread_ API

The code does the checks on should_stop variable in the kernel
threads. The uisthread_stop function sets the should_stop and calls
KILL (eventually kill_pid) to stop the thread.

The checking of should_stop variable can be replaced to a call to
kthread_should_stop function and the setting of the should_stop and
a call to KILL can be replaced with kthread_stop function.

Subject: staging: unisys: Rework Kconfig dependencies

I find the Kconfig dependencies of the various Unisys drivers rather
confusing. Due to the dependencies, you must select the drivers one by
one to see the following ones. So if you are looking for a specific
driver, it is not visible by default. And if you don't know exactly
what you need, it's even worse as you don't know what is available.

In a case like this with several helper drivers and many dependencies,
I think it makes more sense to list all the drivers at first, and use
select statements to fulfill the dependencies for the user.

As a nice side effect, it avoids the weird indentation, which was
technically correct but still somewhat confusing.

I also dropped the dependencies on HAS_IOMEM, as the whole driver set
is for X86_64 only anyway which always has HAS_IOMEM set. And I
dropped the redundant dependencies on UNISYSSPAR as all drivers are
already inside an "if UNISYSSPAR" block.

Subject: staging: lustre: Use kasprintf.

This patch uses kasprintf as it combines kmalloc and
sprintf, and takes care of the size calculation itself.

The semantic patch that makes this change is as follows:

expression list args;
statement S;
@@

  a =
-  \(kmalloc\|kzalloc\)(...,flag)

Subject: staging: rtl8188eu: Compress two statements into one.

This patch removes the use of a variable used only for
returning a value. The following coccinelle script was
used to discover it:

@@
expression ret;
identifier f;
@@

-ret =

     f(...);

It also fixes the checkpatch.pl warning about line being over
80 characters, in the lines where changes were made.

Subject: Staging: rtl8712: Eliminate use of _set_timer

This patch introduces the use of API function mod_timer
instead of driver specific function _set_timer as it is
a more efficient and standard way to update the expire
field of an active timer. Also, definition of function
_set_timer is removed as it is no longer needed after
this change.

Here, these cases are handled using Coccinelle and
semantic patch used for this is as follows:

@@ expression x; expression y;@@

- _set_timer (&x, y);
+ mod_timer (&x, jiffies + msecs_to_jiffies (y));

This is done using Coccinelle and semantic patch used for
this is as follows:

Subject: Staging: rtl8192u: Replace printk() with netdev_dbg()

For dynamic debugging netdev_dbg (if there is a ponterto a device
net structure) is preferred over printk(), which is the raw way
to print something. Issue found by checkpatch.pl.

Subject: Staging: rtl8192e: Use ether_addr_copy() instead of memcpy()

This patch replaces memcpy with ether_addr_copy.
Also pathole was used to make sure that arguments passed to ether_addr_copy
are aligned to u16.
First argument is iwe.u.ap_addr.sa_data i output of pahole is:
struct iw_event {
	__u16                      len;                  /*     0     2 */
	__u16                      cmd;                  /*     2     2 */

	/* XXX 4 bytes hole, try to pack */

	union iwreq_data           u;                    /*     8    16 */

	/* size: 24, cachelines: 1, members: 3 */
	/* sum members: 20, holes: 1, sum holes: 4 */
	/* last cacheline: 24 bytes */
};
and inside union iwreq_data u is sa_data:
struct sockaddr {
/* typedef sa_family_t -> __kernel_sa_family_t */ short unsigned int sa_family; /*     8     2 */
char       sa_data[14];                                          /*    10    14 */
} ap_addr; /*          16 */

sa_data is a char array of size 14, and the number of bytes copied using
ether_addr_copy() is 6.

Second argument is network->bssid and output of pahole is:
struct rtllib_network {
	u8                         bssid[6];             /*     0     6 */

From 8faeebdf1535e61baab53daeca12f2e8a0071db7 Mon Sep 17 00:00:00 2001
From: Joe Perches

Subject: staging: lustre: Convert "return seq_printf(...)" uses

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
     seq_has_overflowed() and make public")

Convert these "return seq_printf(...)" uses to:

	seq_printf(seq, ...);
	return 0;

Done via cocci script:

@@
struct seq_file *seq;
@@

-	return
	\(seq_printf\|seq_puts\|seq_putc\)(seq,
	...);

+	return 0;

With some additional reformatting and typing post conversion.

Miscellanea:

o convert an rc++ use to a bool
o use seq_puts with fixed strings where appropriate

Subject: staging: lustre: Convert seq_ hash functions to return void

These functions don't need to return anything.
No caller uses the return value.

Miscellanea:

Integrate the individual strings to reduce object size ~100 bytes.

Subject: staging: lustre: Convert remaining uses of "= seq_printf(...)"

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
     seq_has_overflowed() and make public")

Convert the remaining uses by hand.

Miscellanea:

o Convert fixed string output to seq_puts

Subject: staging: lustre: resolves sparse warnings using static declaration

This patch resolves sparse warnings about non-declared symbol in
staging/lustre/lustre/lov by adding static declaration.
These warnings are like this:
	warning: symbol 'fiemap_calc_fm_end_offset' was not declared. Should it be static?

Subject: staging: android: ion: fix some format strings

C99 says that a precision which is simply '.' with no following digits
or * should be interpreted as 0, which means that these format strings
actually mean 'print 16 spaces'. However, the kernel's printf
implementation treats this case as if the precision was omitted. Don't
rely on that quirk.

Subject: staging: comedi: ni_labpc_common: fix logically dead code issue

The quick exit check of (mode == MODE_SINGLE_CHAN) results in coverity
reporting a logically dead code issue in the switch code in
labpc_ai_check_chanlist().

Remove the quick exit check and allow the function to handle the
MODE_SINGLE_CHAN normally (the for loop will only happen 1 time and
the function will return 0).

Subject: staging: comedi: rtd520: remove unnecessary interrupt disable

The read/write of the PLX_INTRCS_REG during the driver detach is not
necessary. The rtd_reset() function writes 0 to this register which
will disable all interrupts.

This also fixes a dereference after null check reported by coverity.

Subject: staging: comedi: comedi_8254: introduce module for 8254 timer support

A 8254 timer/counter is commonly used on data acquisition boards to provide
the internal pacer clock used to acquire analog input samples. Some boards
also to allow the timers to be used externally.

Currently the 8254 timers are supported by comedi using the 8253.h header
and a number of inline functions. This works for the internal pacer clock
but requires the drivers to implement subdevice code necessary to use the
timers externally.

Introduce a new module to support both the internal pacer clock and the
external counter subdevice. This will allow removing a bunch of duplicated
code in the drivers and standardizes the comedi 8254 timer support.

This implementation is based on the 8253.h inline functions and the various
subdevice functionality in the comedi drivers.

+/*
+ * Module: comedi_8254
+ * Description: Generic 8254 timer/counter support
+ * Author: H Hartley Sweeten <hsweeten@visionengravers.com>
+ * Updated: Thu Jan 8 16:45:45 MST 2015
+ * Status: works
+ *
+ * This module is not used directly by end-users. Rather, it is used by other
+ * drivers to provide support for an 8254 Programmable Interval Timer. These
+ * counters are typically used to generate the pacer clock used for data
+ * acquisition. Some drivers also expose the counters for general purpose use.
+ *
+ * This module provides the following basic functions:
+ *
+ * comedi_8254_init() / comedi_8254_mm_init()
+ *	Initializes this module to access the 8254 registers. The _mm version
+ *	sets up the module for MMIO register access the other for PIO access.
+ *	The pointer returned from these functions is normally stored in the
+ *	comedi_device dev->pacer and will be freed by the comedi core during
+ *	the driver (*detach). If a driver has multiple 8254 devices, they need
+ *	to be stored in the drivers private data and freed when the driver is
+ *	detached.
+ *
+ *	NOTE: The counters are reset by setting them to I8254_MODE0 as part of
+ *	this initialization.
+ *
+ * comedi_8254_set_mode()
+ *	Sets a counters operation mode:
+ *		I8254_MODE0	Interrupt on terminal count
+ *		I8254_MODE1	Hardware retriggerable one-shot
+ *		I8254_MODE2	Rate generator
+ *		I8254_MODE3	Square wave mode
+ *		I8254_MODE4	Software triggered strobe
+ *		I8254_MODE5	Hardware triggered strobe (retriggerable)
+ *
+ *	In addition I8254_BCD and I8254_BINARY specify the counting mode:
+ *		I8254_BCD	BCD counting
+ *		I8254_BINARY	Binary counting
+ *
+ * comedi_8254_write()
+ *	Writes an initial value to a counter.
+ *
+ *	The largest possible initial count is 0; this is equivalent to 2^16
+ *	for binary counting and 10^4 for BCD counting.
+ *
+ *	NOTE: The counter does not stop when it reaches zero. In Mode 0, 1, 4,
+ *	and 5 the counter "wraps around" to the highest count, either 0xffff
+ *	for binary counting or 9999 for BCD counting, and continues counting.
+ *	Modes 2 and 3 are periodic; the counter reloads itself with the initial
+ *	count and continues counting from there.
+ *
+ * comedi_8254_read()
+ *	Reads the current value from a counter.
+ *
+ * comedi_8254_status()
+ *	Reads the status of a counter.
+ *
+ * comedi_8254_load()
+ *	Sets a counters operation mode and writes the initial value.
+ *
+ * Typically the pacer clock is created by cascading two of the 16-bit counters
+ * to create a 32-bit rate generator (I8254_MODE2). These functions are
+ * provided to handle the cascaded counters:
+ *
+ * comedi_8254_ns_to_timer()
+ *	Calculates the divisor value needed for a single counter to generate
+ *	ns timing.
+ *
+ * comedi_8254_cascade_ns_to_timer()
+ *	Calculates the two divisor values needed to the generate the pacer
+ *	clock (in ns).
+ *
+ * comedi_8254_update_divisors()
+ *	Transfers the intermediate divisor values to the current divisors.
+ *
+ * comedi_8254_pacer_enable()
+ *	Programs the mode of the cascaded counters and writes the current
+ *	divisor values.
+ *
+ * To expose the counters as a subdevice for general purpose use the following
+ * functions a provided:
+ *
+ * comedi_8254_subdevice_init()
+ *	Initializes a comedi_subdevice to use the 8254 timer.
+ *
+ * comedi_8254_set_busy()
+ *	Internally flags a counter as "busy". This is done to protect the
+ *	counters that are used for the cascaded 32-bit pacer.
+ *
+ * The subdevice provides (*insn_read) and (*insn_write) operations to read
+ * the current value and write an initial value to a counter. A (*insn_config)
+ * operation is also provided to handle the following comedi instructions:
+ *
+ *	INSN_CONFIG_SET_COUNTER_MODE	calls comedi_8254_set_mode()
+ *	INSN_CONFIG_8254_READ_STATUS	calls comedi_8254_status()
+ *
+ * The (*insn_config) member of comedi_8254 can be initialized by the external
+ * driver to handle any additional instructions.
+ *
+ * NOTE: Gate control, clock routing, and any interrupt handling for the
+ * counters is not handled by this module. These features are driver dependent.

Subject: staging: comedi: add 'pacer' member to struct comedi_device

Add a new member to the comedi_device struct for a comedi_8254 'pacer'. This
provides a convient place to store the data allocated by the comedi_8254 module
for boards that use an 8254 device to create the data acquisition pacer clock.

Automatically free this pointer in comedi_device_detach_cleanup() so that the
drivers don't need to do it when then are detached.

Subject: staging: comedi: pcl812: convert driver to use the comedi_8254 module

This driver uses an 8254 timer to generate the pacer clock used for analog
input data acquisition. Convert it to use the comedi_8254 module to provide
support for the 8254 timer.

Note that the pacer does not have to be stopped when starting a new async
command in pcl812_ai_cmd() or when the card is initialy reset by pcl812_reset().
The counters are all reset when the driver is initially attached and the
counters used by the pacer are stopped when a command is canceled.

Subject: staging: comedi: pcl818: convert driver to use the comedi_8254 module

This driver uses an 8254 timer to generate the pacer clock used for analog
input data acquisition. Convert it to use the comedi_8254 module to provide
support for the 8254 timer.

Note that the pacer does not have to be stopped when starting a new async
command in pcl818_ai_cmd() or when the card is initialy reset by pcl818_reset().
The counters are all reset when the driver is initially attached and the
counters used by the pacer are stopped when a command is canceled.

Subject: staging: comedi: cb_pcidas: convert driver to use the comedi_8254
 module

This driver uses two 8254 timers to generate the pacer clocks. One for analog
input acquisition and one for analog output data conversion. Convert it to use
the comedi_8254 module to provide support for the 8254 timers.

Use the comedi_device 'pacer' member for the 8254 timer used for analog input.
This data is freed automatically by the core during the detach of the driver.

Store the data for the 8254 timer used for analog output in the private data.
This data needs to be freed by the driver when it is detached.

Subject: staging: comedi: das16m1: convert driver to use the comedi_8254
 module

This driver uses two 8254 timers. One to generate the analog input pacer clock and
one to count the number of samples. Convert it to use the comedi_8254 module to
provide support for the 8254 timers.

Use the comedi_device 'pacer' member for the 8254 timer used for analog input. This
data is freed automatically by the core during the detach of the driver.

Store the data for the 8254 timer used to count samples in the private data. This
data needs to be freed by the driver when it is detached.

Subject: staging: comedi: cb_das16_cs: convert driver to use the comedi_8254
 module

The hardware supported by this drive has an 8254 timer. Currently this driver
does not use the timer functions.

For aesthetics, use the comedi_8254 module to provide support for the 8254
timer. This will ensure that the counters are all reset and make it easier
to add functionality later.

Subject: staging: comedi: adv_pci1710: convert driver to use the comedi_8254
 module

This driver uses an 8254 timer to generate the pacer clock used for analog
input data acquisition. It also provides a comedi_subdevice to allow the user
to use channel 0 of the 8254 timer. Currently the subdevice support does not
work correctly due to and (*insn_config) that does not follow the comedi API.

Convert it to use the comedi_8254 module to provide support for the 8254 timer
and proper support for the subdevice.

Subject: staging: comedi: amplc_pci230: convert driver to use the comedi_8254
 module

This driver uses an 8254 timer to generate the pacer clock used for analog
input data conversion. Convert it to use the comedi_8254 module to provide
support for the 8254 timer.

Subject: staging: comedi: das08: convert driver to use the comedi_8254 module

Some of the hardware supported by this driver include an 8254 timer that is
exposed to the user as a comedi_subdevice. Convert it to use the comedi_8254
module to provide support for the 8254 timer.

Subject: staging: comedi: ni_at_ao: convert driver to use the comedi_8254
 module

The hardware supported by this driver includes an 8254 timer. This timer is
not currently used, other than setting counters 1 and 2 to MODE4 to ensure
that the outputs are high.

For aesthetics, convert it to use the comedi_8254 module to provide support
for the 8254 timer. This will make it easier to add features later.

Subject: staging: comedi: das6402: convert driver to use the comedi_8254
 module

This driver uses an 8254 timer to generate the pacer clock used for analog
input data conversion. Convert it to use the comedi_8254 module to provide
support for the 8254 timer.

Remove the unnecessary programming of timer 0. The private data 'count'
value is never set by the driver and the timer is reset to MODE0 when
the timers are initialized during the attach of the driver.

Remove the unnecessart convert_src check in the (*do_cmdtest). The only
valid convert_src is TRIG_TIMER.

Subject: staging: comedi: das1800: convert driver to use the comedi_8254
 module

This driver uses an 8254 timer to generate the pacer clock used for analog
input data conversion. Convert it to use the comedi_8254 module to provide
support for the 8254 timer.

Tidy up the (*do_cmdtest) validation of the timer arguments.

Absorb the converted das1800_setup_counters() code into the (*do_cmd).

Subject: staging: comedi: adv_pci_dio: simplify counter subdevice I/O

Only two of the boards supported by this driver have an 8254 counter/timer.
Both of these boards have a single 8254 device. Currently the counter
subdevice functions are coded to support multiple 8254 devices. This is
unnecessary and just complicates the code.

Simplfy the subdevice functions to work for a single 8254 counter/timer and
refactor the driver (*attach) accordingly.

Subject: staging: comedi: adv_pci_dio: refactor 's8254' boardinfo

The boardinfo for the 8254 timer is overly complex. The 8254 timer always has
3 channels and the 'regs' and 'specflags' members of diosubd_data are not
used. The only necessary information is the base 'addr' offset to the 8254
registers.

Replace the 's8254' member with an unsigned long 'timer_regbase'. Use that
to determine if the board has an 8254 timer during the attach of the driver.
Save the 'timer_regbase' in the subdevice 'private' pointer to use in the
subdevice functions.

For aesthetics, absorb pci_dio_add_8254() into the driver attach function.

Subject: staging: comedi: me4000: convert driver to use the comedi_8254 module

Some of the hardware supported by this driver include an 8254 timer. For
aesthetics, convert it to use the comedi_8254 module to provide support for
the 8254 timer.

This also fixes the (*insn_read) and (*insn_write) to work like the comedi
API expects. Currently they only read or write a single value.

It also fixes the (*insn_config). Currently the driver is attempting to
handle the configuration instructions GPCT_RESET and GPCT_SET_OPERATION.
These are just arbitrary valuse and are not real comedi configuration_ids.
They actually coorespond to:

  GPCT_RESET -> INSN_CONFIG_DIO_OUTPUT
  GPCT_SET_OPERATION -> INSN_CONFIG_ANALOG_TRIG

The number of parameters for the instructions is validated by the comedi
core in check_insn_config_length(). GPCT_RESET happens to work (insn->n == 1)
but GPCT_SET_OPERATION would fail. The INSN_CONFIG_ANALOG_TRIG expects
insn->n == 5 but GPCT_SET_OPERATION in this driver expects insn->n == 2.

Subject: staging: comedi: amplc_dio200_common: remove unnecessary
 'counter_number' checks

The 'counter_number' in these functions is the comedi channel number from the
chanspec. The comedi core validates the chanspec before calling the driver
functions. Remove the unnecessary checks.

Subject: staging: comedi: amplc_dio200_common: remove 'spinlock' from struct
 dio200_subdev_8254

Currently this driver uses a spinlock in the 8254 subdevice (*insn_read), (*insn_write),
and (*insn_config) functions. The comedi core checks if the subdevice is 'busy', in
parse_insn(), before any of the subdevice functions are attempted.

Remove the unnecessary spinlock.

Subject: staging: comedi: ni_labpc_common: convert driver to use the
 comedi_8254 module

This driver uses an 8254 timer to generate the pacer clock used for analog
input data conversion. Convert it to use the comedi_8254 module to provide
support for the 8254 timer.

The hardware actually has two 8254 devices. Timer B0 is the master for timed
conversions, timer B1 sets the scan pacing, and tmer A0 sets the conversion
pacing.

For the conversion, dev->pacer is used for the "B" timers and a new private
data member, dev->counter, is used for the "A" timers. All the divisor values
are stored in the dev->pacer.

Subject: staging: comedi: cb_pcimdas: fix analog input channel configuration

The hardware uses a switch on the board to set the number of analog
input channels to either 16 single-ended or 8 differential channels.
Currently the switch setting is checked for every (*insn_read) operation
to validate the channel number.

Check the switch setting during the driver attach and initialize the
subdevice accordingly. This allows the core to handle the validation.

Subject: staging: comedi: cb_pcimdas: support analog input programmable ranges

The hardware uses a switch on the board to select if the analog inputs
are bipolar or uinipolar. The gain is programmable to allow the following
input ranges:

  Gain  Bipolar   Unipolar
    0   +/-10V    0 to 10V
    1   +/-5V     0 to 5V
    2   +/-2.5V   0 to 2.5V
    3   +/-1.25V  0 to 1.25V

Add the necessary code to the driver to allow the user to select the
desired range.

Subject: staging: comedi: cb_pcimdas: tidy up cb_pcimdas_auto_attach()

For aesthetics, add some whitespace to the subdevice init.

Remove the unnecessary comments as well as the initialization of the
analog input subdevice 'len_chanlist'. That member is only used by
subdevices that support async commands.

For aesthetics, rename the analog input subdevice (*insn_read) function.

Subject: staging: comedi: adl_pci6208: combine PCI-6208 and PCI-6216 support

This module's PCI device table has separate PCI device IDs for PCI-6208
and PCI-6216, but in reality, both boards and their cPCI and PCIe
variants seem to have the same PCI device ID: 0x6208.  The PCI subdevice
ID doesn't seem to help either.

It shouldn't do any harm to claim 16 AO channels for all devices
supported by this driver.  The original PCI-6216 is just a PCI-6208 with
a daughter board providing the extra DACs.  The data is clocked out to
the DACs serially with no acknowledgment.  I assume this would still
happen when the DACs for the upper 8 channels are missing.  Therefore,
change the driver to support a single board type with 16 AO channels,
and remove the suspicious PCI device ID for the PCI-6216.

Evidence about lack of a separate PCI device ID for PCI-6216 follows....

1. Jesus Vasquez reports the following lspci output for a PCIe-6216 on
his Ubuntu 12.04 system:

lspci -n -vvv
07:00.0 1180: 144a:6208 (rev 02)
        Subsystem: 144a:6208

        Region 0: Memory at f6000000 (32-bit, non-prefetchable)

        Region 1: I/O ports at c100 [size=128]
        Region 2: I/O ports at c000 [size=256]
        Kernel driver in use: adl_pci6208
        Kernel modules: adl_pci6208

That system's "adl_pci6208" module only has the single PCI device ID for
the PCI-6208, but works for his PCIe-6216 except that it only supports 8
analog output channels instead of 16.

2. ADLINK's binary Linux module "pci6208.ko" (there is no separate
module for the PCI-6216) has a single alias:

  alias: pci:v0000144Ad00006208sv*sd*bc*sc*i*

3. The MS Windows drivers include this set of hardware IDs for the
PCI-6208 series, with nothing more specific for the PCI-6216 (they are
all tied to the same name "ADLINK PCI-6208" and there is no mention of
PCI-6216):

  PCI\VEN_10B5&DEV_9050&SUBSYS_62089999
  PCI\VEN_144A&DEV_6208&SUBSYS_6208144A

Subject: staging: comedi: adl_pci6208: remove multiple board type support

This driver module now only supports a single board type, so remove the
infrastructure for describing multiple board types.  The comedi
"auto_attach" handler, `pci6208_auto_attach()` doesn't need to set the
comedi device's `board_name` or `board_ptr` members.  The former is
automatically pointed to the comedi driver's `driver_name` by the core
comedi module, and the latter is not used anywhere else.  The AO
subdevice's `n_chans` member can be set to 16 without looking it up in
the single element of `pci6208_boards[]`.  There is no need to pass a
board index from the PCI device table to the "auto_attach" handler.

Subject: staging: comedi: adl_pci6208: support old PLX device ID

ADLINK's MS Windows drivers for the PCI-6208/6216 boards include the
following line in the DDInstall secion of the INF file:

%String6208%=DriverInstall6208.NT,PCI\VEN_10B5&DEV_9050&SUBSYS_62089999

That's for a PLX PCI 9050/9052 PCI interface chip with custom subvendor
and subdevice ID.  The "%String6208%" macro expands to "ADLINK PCI-6208"
in the INF file.

Add a corresponding entry to this driver module's PCI device table.

Subject: staging: lustre: Convert uses of "int rc = seq_printf(...)"

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
     seq_has_overflowed() and make public")

Convert these uses to:

	seq_printf(seq, ...);

	return 0;

Done via cocci script:

@@
struct seq_file *seq;
int i;
@@
-	i = seq_printf(seq,
+	seq_printf(seq,
		   ...);
	...
-	return i;
+	return 0;

@@

-	i += seq_printf(seq,
+	seq_printf(seq,
	           ...);
	...
-	return i;
+	return 0;

With some additional reformatting and typing post conversion
to remove the now unnecessary "int i;" declaration.

Subject: staging/lustre/llite: Fix obd name after c&p error

commit 95745e9b1de2 ("staging: lustre: Use kasprintf.") introduced
a copy and paste error causing two different obd types to be assigned
same content causing lustre to fail on mount with a warning from procfs
followed by a bizzare error about OST not having enough MDS
capabilities.

This patch unbreaks Lustre client again.

Subject: Staging: emxx_udc: Replace custom printk macro ERR with dev_err or
 pr_err

This patch removes the use of custom printk macros ERR and replace it
with dev_err, or pr_err in the following cases:
- if no appropriate struct device *dev field where found for dev_err.
- or dev could be null eg. "dev_err(udc->dev" not possible inside "if
  (udc == null)"
Issue addressed by checkpatch.pl.

This patch removes a if condition which has a semicolon
after it. As the conditional check is redundant, the comment
before it is also changed. The following
coccinelle script was used to detect the pattern of a
semicolon after if.

Subject: staging: iio: meter: add check on return variables

adds checks on variables that are used to return values. If
the value is less than zero, this indicates that an error
occurred and hence a message is printed through dev_err.
Checks are made on negative values only since spi_* functions
return negative error codes.

The functions were found using the following script but the
aforementioned modification was what was carried out in the end:

Subject: Staging: rtl8712: Eliminate use of _init_timer

This patch introduces the use of API function setup_timer
instead of driver specific function _init_timer as it is
the preferred and standard way to setup and set the timer.
To be compatible with the change, argument types of
referenced functions are changed. Also, definition of
function _init_timer is removed as it is no longer needed
after this change.

This is done using Coccinelle and semantic patch used for
this is as follows:

@@ expression x, y; identifier a, b;@@

- _init_timer (&x, y, a, b);
+ setup_timer (&x, a, (unsigned long)b);

Subject: staging: rtl8192e: Remove if conditions.

This patch removes if conditions with no exececutable
statements in the bodies of those ifs and also no variable
assignments in the if conditional checks. The call to
rtllib_act_scanning in the condition doesn't have any side
effects as it too performs conditional checks without changing
any values. Hence, it's safe to remove the if condition.

Subject: Staging: media: clean dev_err logging

This patch removes  __func__ from dev_err. dev_err includes information about:
(devcice, driver, specific instance of device, etc) in the log printout.
This was done using Coccinelle, with the following semantic patch:

@a@
expression E, R;
expression  msg;
@@

dev_err(E, msg, __func__, R);

@script:python b@
e << a.msg;
y;
@@

if(e.find("%s: ") == True):
	m = e.replace("%s: ", "", 1);
	coccinelle.y = m;
elif(e.find("%s ") == True):
	m = e.replace("%s ", "", 1);
	coccinelle.y = m;
elif(e.find("%s:") == True):
	m = e.replace("%s:", "", 1);
	coccinelle.y = m;
else:
	m = e.replace("%s", "",1);
	coccinelle.y = m;

@c@
expression a.E, a.msg, a.R;
identifier  b.y;
@@

- dev_err(E, msg, __func__, R);
+ dev_err(E, y, R);

Subject: staging/lustre/ptlrpc: Do not use deprecated cpus_* functions

As per Rusty Russel, cpus_* functions are deprecated.
When mixing cpumask_copy with cpus_weight, they operate on different
sized masks if CPUMASK_OFFSTACK is enabled, causing an
immediate assertion failure.
Copying of cpumasks by assignment is also not allowed now.

Additionally, in ptlrpc/service.c avoid the cpumask copies,
since we only use it to check how many siblings are there for
core #0 and nothing else.

Subject: staging/lustre/libcfs: replace deprecated cpus_ calls with cpumask_

Rusty Russel advises that cpus_* functions are deprecated to work
on cpumasks and cpumask_* functions should be called instead,
otherwise problems with CPUMASK_OFFSTACK arise.

Subject: staging: vt6656: Fix possible leak in vnt_download_firmware()

When failing to allocate buffer memory, function vnt_download_firmware() goes
through the wrong exit path and fails to release the already requested
firmware. Thus use the correct cleanup. Detected by Coverity CID 1269128.

+TODO:
+- lots of clechpatch cleanup
+- use kernel coding style
+- refine the code and remove unused code
+- check on hardware effects of removal of USE_HW_I2C and USE_DVICHIP (these two
+	are supposed to be sample code which is given here if someone wants to
+	use those functionalities)
+- move it to drivers/video/fbdev
+- modify the code for drm framework
+
+Please send any patches to

+Introduction:
+	SM750 of Silicon MOtion is pci express display controller device.
+	The SM750 embedded graphics features include:
+	- dual display
+	- 2D acceleration
+	- 16MB integrated video memory
+
+About the kernel module paramter of driver:
+
+	Use 1280,8bpp index color and 60 hz mode:
+	insmod ./sm750fb.ko g_option="1280x1024-8@60"
+
+	Disable MTRR,Disable 2d acceleration,Disable hardware cursor,
+	and use a 800x600 mode :
+	insmod ./sm750fb.ko g_option="noaccel:nomtrr:nohwc:800x600"
+
+	dual frame buffer for driver with "dual" parameter
+	insmod ./sm750fb.ko g_option="dual,800x600:1024x768"
+	it will create fb0 and fb1 (or fb1,fb2 if fb0 already exist) under /dev
+	and user can use con2fb to link fbX and ttyX
+
+	Notes:
+	1) if you build the driver with built-in method, the paramter
+		you edited in the grub config file will be also the
+		same format as above modular method,but additionaly add
+		"video=sm750fb:"
+		ahead of parameters,so,it looks like:
+		video=sm750fb:noaccel,1280x1024@60,otherparam,etc...
+		it equal to modular method with below command:
+		insmod ./sm750fb.ko g_option="noaccel:1280x1024@60:otherparm:etc..."
+
+	2) if you put 800x600 into the paramter without bpp and
+		refresh rate, kernel driver will defaulty use 16bpp and 60hz
+
+Important:
+	if you have vesafb enabled in your config then /dev/fb0 will be created by vesafb
+	and this driver will use fb1, fb2. In that case, you need to configure your X-server
+	to use fb1. Another simple althernative is to disable vesafb from your config.

Subject: Staging: fbtft: add header for internal functions

Remove extern keyword from function prototypes to suppress warning from
checkpatch.pl with --strict option: https://lkml.org/lkml/2013/7/23/422

fbtft maintainer Noralf Tronnes advised these functions are internal to
this module & suggested moving these prototypes to new internal.h file.
He also advised fbtft.h file will eventually live in include/linux/fbtft.h

The messages put out by these macros are for driver debugging and aren't needed
any more, so just remove all use of them, and the macros too.

Subject: staging: unisys: remove ASSERT() macro

Remove the ASSERT macro from timskmod.h, and replace its single use with
WARN_ON() instead.

Subject: staging: unisys: remove ERRDEV macros

Remove the LOGERR, LOGERRDEV, LOGERRDEVX, LOGERRNAME, LOGORDUMPERR
macros from all the drivers.

In one case the removal of the ERRDRV() changed things such that a macro which
returned a value was needed, but the return value was no longer being used. In
this case the macro was replaced with the contents of the macro, but with the
truth calculation removed so that it would not generate a warning.

Subject: staging: unisys: remove LOGWRN() macros and uniklog.h

Remove the last set of macros from uniklog.h. Without LOGWRN() and
friends, uniklog.h is empty so we can delete the file itself as well.

This macro was not used a lot but the file was included in many places.

This implements more granular locking in vme_user_ioctl() by using separate
locks for each devfs device.

This also provides a synchronization between vme_user_read(), vme_user_write()
and vme_user_ioctl().

Subject: vme: tsi148: Master windows support USERx and CR/CSR accesses, not
 slaves

The tsi148 driver is registering the slave images as supporting the "USER"
access modes and CR/CSR access mode rather than the master images as it
should.

Remove the incorrect case entries for these modes from the
tsi148_slave_set() function, stop registering slave_images as supporting
these modes and instead register master windows as supporting these modes.

Subject: staging: rtl8723au: Clean up PHY_{Query,Set}BBReg() 32 bit
 read/writes

This switches pure 32 bit read/writes to use the
rtl8723au_{read,write}32() functions directly.

Subject: staging: rts5208: Convert variable from int to bool and propagate the
 change to function parameters

This patch convert local variables declared as int into booleans.
It also propagates the conversion when these variables were used
as function parameters.

Coccinelle was used to generate this patch.

+	  module of the QorIQ LS2 SoCs, that does resource management
+	  for hardware building-blocks in the SoC that can be used
+	  to dynamically create networking hardware objects such as
+	  network interfaces (NICs), crypto accelerator instances,

Subject: staging: fsl-mc: fsl-mc object allocator driver

The fsl-mc object allocator driver manages "allocatable" fsl-mc
objects such as DPBPs, DPMCPs and DPCONs. It provides services to
other fsl-mc drivers to allocate/deallocate these types of objects.

Subject: Staging: iio: Change data type to u16 to avoid unnecessary typecast

In the adis16220_read16bit() function we earlier used a s16 value 'val'
which is used by the adis_read_reg_16 function to read data and takes a
u16 value as a parameter.

So, this patch changes the data type of 'val' from s16 to u16. It is safe
to remove the extra sign extension, since the user of the function uses it
to read a 10 unsigned value which will lead to the same result in both cases.
Further this patch removes the unnecessary typecast for the simplification of
code. In addition to this, initialization of 'val' to 0 is also dropped. This is
due to the fact that not initializing helps the compiler provide useful warnings
if the code gets changed to return an otherwise uninitialized result.

Subject: drivers: staging: iio: accel: Removed unnecessary variable

Variable len is used only to store the return value. Hence len is
removed and the return statement modified. Coccinelle was used to
detect such removable variables:

-ret =

Subject: iio: gyro: itg3200: add suspend/resume support.

Unless we put the device to sleep when not it use, it wastes
6mA.

If the device is asleep on probe, the 'id' register
sometimes mis-reads - so reset first.  If the device responds
at all a command sent to the address, it is almost certainly
the correct device already.

Subject: staging: iio: Documentation: Introduce iio_utils.c

This patch removes inline functions from iio_utils.h in order to clean the
code. iio_utils.c contains the implementation of the functions used by
iio_event_monitor.c, lsiio.c or generic_buffer.c and iio_utils.h contains
the declarations of these functions.

Since iio_utils.h is modified, generic_buffer.c and iio_event_monitor.c
must include stdlib.h.

Subject: tools: iio: Define _GNU_SOURCE in Makefile

Definition of _GNU_SOURCE is needed to get rid of some warnings, such
as:
warning: implicit declaration of function `asprintf'.

generic_buffer.c and iio_event_monitor.c define _GNU_SOURCE,
but it is also needed in lsiio.c and iio_utils.c. For this reason,
this patch adds the definition in Makefile and removes it from where
it already exists.

Subject: staging: sm750fb: wrong type for print

mention correct format specifier while printing.
fixes all the build warnings about incorrect argument type while
printing.
since this is a framebuffer device and it should follow what the
framebuffer layer is suggesting in struct fb_fix_screeninfo at
smem_start and mmio_start, so accordingly changed the datatypes of
vidmem_start, vidreg_start, vidmem_size and vidreg_size.

Subject: staging: sm750fb: fix undeclared function

kbuild test robot reported that for microblaze-allyesconfig
chan_to_field() and lynxfb_ops_set_par() were not defined. These two
functions were defined under CONFIG_PM, so for any archtecture if
CONFIG_PM is not defined we will have this error.

while moving the lynxfb_suspend() function some very obvious
checkpatch errors, like space after comma, space after if, space
before opening brace, were taken care of.

From: Lorenzo Stoakes

Subject: staging: sm750fb: Cleanup the type of mmio750

This patch assigns the more appropriate void* type to the mmio750 variable
eliminating an unnecessary volatile qualifier in the process. Additionally it
updates parameter types as necessary where those parameters interact with
mmio750, removes unnecessary casts and updates the type of the
lynx_share->pvReg field which is passed to the ddk750_set_mmio method.

As a consequence, this patch fixes the following sparse warning:-

drivers/staging/sm750fb/ddk750_help.c:12:17: warning: incorrect type in assignment (different address spaces)

Subject: Staging: sm750fb: fix build warning with lynx_accel

Change the return value of lynx_accel to be void, to fix the build
warning, and due to the fact that the function can't seem to fail at
all, and no one cares if it does or not.

Subject: Staging: sm750fb: provide error path for hw_sm750le_setBLANK()

This provides a default path for the switch statement in
hw_sm750le_setBLANK() so that the compiler will not correctly complain
about undefined values being sent to the hardware.

Instead, properly error out if the blank command is unknown by the
driver.

Subject: dgnc: Make all lines under 80 characters in dgnc_cls.h

Some of the lines are over 80 characters so fix that by moving the
comments before the struct definition and before #define's.

Subject: dgnc: Make all lines under 80 characters in dgnc_driver.c

Some of the lines are over 80 characters in dgnc_driver.c so fix them by
moving the comments closer to the code, tidying the comments to make
them smaller, and remove a redundant space after +.

Subject: staging: dgnc: off by one in dgnc_mgmt_ioctl()

"dgnc_NumBoards" is the number of initialized elements in the
dgnc_Board[] array so the comparison should be ">=" instead of ">" so we
don't read invalid data.  We can remove the special handling of the
empty array now that we've fixed this bug.

Subject: dgnc: clean up comments at start of files

Remove FSF address because it's known in the past that it has changed.
Also, remove the pointless "do not change the coding style" comments
because it's one of the reasons why it's in staging and it's quite
contradictory to what it says in TODO. Also, they contain wrong e-mails
of people which are responsible for these drivers - see TODO or
MAINTAINERS for that. We can preserve the original copyright at the top
of the most files because it shows who originally made them.

This patch removes the redundant parentheses inorder to make code
simplified. While doing this, the precedence order of the operation
is taken into consideration to keep the logic of the code intact.

Subject: Staging: dgnc: Use goto for spinlock release before return

spin_unlock_irqrestore() is called at several
different places before exiting. This patch uses a goto statement
to factorize these calls.

Coccinelle was used to generate this patch.

Subject: iio: bmc150: introduce bmc150_accel_interrupt

Since both triggers and events can share an interrupt, add a data
structure that tracks the users of an interrupt so that it enables or
disables it only for the first users and respectively last user.

This will allows us to easily add more events or triggers.

The patch also adds an interrupt enabled counter, so that we can
easily know if we need to put the device in normal mode when the
resume callback is issued.

Subject: iio: bmc150: introduce bmc150_accel_trigger

Add a separate structure for triggers and add the infrastructure to
support an arbitrary number of triggers. Each trigger is associated
with an interrupt and has an enabled/disabled state.

Subject: iio : Add ABI documentation for thresh falling/rising value in accel

This patch adds ABI documentation entries for
in_accel_thresh_falling_value, and in_accel_thresh_rising_value in /events.
There is at least one user for these, lis3l02dq in accel.

This patch removes a redundant variable "val" and adds
inline return statements. It also adds a default case
to the switch statement which returns 0 to keep the logic
intact.

It also removes a redundant variable "inx" and adds inline
return statements.

Subject: Staging: rtl8192u: Add function to improve code quality

This patch introduces a new function for the authentication response
error check in the  ieee80211_rx_frame_softmac() function to fix the
indentation problem. It also adds the iotAction variable in the new
function to fix the "more than 80 characters per line" warning.

Subject: Staging: lustre: Iterate list using list_for_each_entry

Code using doubly linked list is iterated generally  using list_empty and
list_entry functions, but it can be better written using list_for_each_entry
macro.

This patch replaces the while loop containing list_empty and list_entry with
list_for_each_entry and list_for_each_entry_safe. list_for_each_entry is a
macro which is used to iterate over a list of given type. So while loop used to
iterate over a list can be replaced with list_for_each_entry macro. However, if
list_del is used in the loop, then list_for_each_entry_safe is a better choice.
This transformation is done by using the following coccinelle script.

@ rule1 @
expression E1;
identifier I1, I2;
type T;
iterator name list_for_each_entry;
@@

- while (list_empty(&E1) == 0)
+ list_for_each_entry (I1, &E1, I2)
 {
	...when != T *I1;
- 	I1 = list_entry(E1.next, T, I2);
    ...when != list_del(...);
       when != list_del_init(...);
 }

@ rule2  @
expression E1;
identifier I1, I2;
type T;
iterator name list_for_each_entry_safe;
@@
   T *I1;
+  T *tmp;
  ...
- while (list_empty(&E1) == 0)
+ list_for_each_entry_safe (I1, tmp, &E1, I2)
 {
	...when != T *I1;
- 	I1 = list_entry(E1.next, T, I2);
    ...
 }

Parentheses removal were left to the script. However, handling pointer
casts were done manually because not all replacements generated by the
script were suitable. In general, the following cases were discarded:

pointer casts in macros,
pointer casts on function arguments in the form of:
<func>(...,(<type> *)&<expression>,...)

since both cases generated compilation warnings.

Subject: staging: ft1000: ft1000-usb: adjust function arguments

Handles the following issues:

Removing extra parentheses around function arguments,
Removing unnecessary pointer to pointer cast.

Issues were detected using the following coccinelle script:

@@
expression e;
type t;
identifier f;
@@

f(...,
-(t *)
e
,...)

@@
expression e;
identifier f;
@@

f(...,
&
-(
e
-)
,...)

@@
expression e;
identifier f;
@@

f(...,
-(
e

,...)

Parentheses removal were left to the script. However, handling pointer
casts were done manually because not all replacements generated by the
script were suitable. In general, the following cases were discarded:

pointer casts in macros,
pointer casts on function arguments in the form of:
    <func>(...,(<type> *)&<expression>,...)

since both cases generated compilation warnings.

Subject: Staging: comedi: Use function setup_timer for combining
 initialization

The function setup_timer combines the initialization of a timer with the
initialization of the timer's function and data fields.

So, this patch combines the multiline code for timer initialization using the function
setup_timer. This issue is identified via coccinelle script.

Subject: Staging: comedi: Remove parentheses around right side assignment

Parentheses are not needed around the right hand side of an assignment.
This patch remove parenthese of such occurences. Issue was detected and
solved using the following coccinelle script:

@rule1@
identifier x, y, z;
expression E1, E2;
@@

(
x = (y == z);
|
x = (E1 == E2);
|
 x =
-(
...
-)
 ;
)

Subject: Staging: rtl8712: Eliminate use of _cancel_timer_ex

Use timer API function del_timer_sync instead of driver
specific function _cancel_timer_ex as besides deactivating
a timer, it ensures that the timer is stopped on all
CPUs before the driver exists. Also, definition of function
_cancel_timer_ex is removed as it is no longer needed after
this change.

This is done using Coccinelle and semantic patch used for
this is as follows:

@@ expression x; @@

- _cancel_timer_ex (&x);
+ del_timer_sync (&x);

Subject: Staging: rtl8712: Eliminate use of _cancel_timer

Use timer API function del_timer_sync instead of driver
specific function _cancel_timer as besides deactivating
a timer, it also ensures that the timer is stopped on all
CPUs before the driver exists. Also, variables
timer_cancelled and bool are removed as they are no longer
needed.

Subject: Staging: rtl8192u: Convert use of __constant_<foo> to <foo>

Using functions of the form __constant_<foo> isn't preferred
outside of include/uapi/ as using the function without
__constant_ is identical when the argument is a constant.
So, this patch replaces __constant_htons with htons.

This is done using Coccinelle and semantic patch used for
this is as follows:

@@identifier x;@@

(
- __constant_htons(x)
+ htons(x)
|
- __constant_htonl(x)
+ htonl(x)
|
- __constant_ntohs(x)

Subject: Staging: rtl8192u: Remove unnecessary variable

This patch detects the cases in which a variable is not modified through
the code and it is used as a return value. The variable is detected and
removed by coccinelle using the following semantic patch:

@@ type T; expression expr; identifier r; constant c; @@

-T r = expr;
... when != r
    when strict
-return r;
+return expr;

Subject: Staging: rtl8192e: Remove unnecessary macro

This patch removes the RTLLIB_PRINT_STR macro definition because it's
only defined in the header and it's never referenced. It also removes
PRINTABLE and MAX_STR_LEN, which were defined as helpers for the first
one.

Use msecs_to_jiffies instead of driver specific macro
MSECS. This is done using Coccinelle and semantic
patch used for this is as follows:

Subject: Staging: rtl8188eu: Eliminate use of _set_timer

This patch introduces the use of API function mod_timer
instead of driver specific function _set_timer as it is
a more efficient and standard way to update the expire
field of an active timer. Also, definition of function
_set_timer is removed as it is no longer needed after
this change.

Here, these cases are handled using Coccinelle and
semantic patch used for this is as follows:

@@ expression x; expression y;@@

- _set_timer (&x, y);
+ mod_timer (&x, jiffies + msecs_to_jiffies (y));

From 28af7ea81e161eadb48051ec0e280666e925ccd8 Mon Sep 17 00:00:00 2001
From: Vaishali Thakkar

Subject: Staging: rtl8188eu: Eliminate use of _init_timer

This patch introduces the use of API function setup_timer
instead of driver specific function init_timer as it is
the preferred and standard way to set and setup the timer.
To be compatible with the changes, argument types of
referenced functions are changed. Also, definition of
function _init_timer is removed as it is no longer needed
after this change.

Here, these cases are handled using Coccinelle and
semantic patch used for this is as follows:

@@ expression x, y; identifier a, b;@@

- _init_timer (&x, y, a, b);
+ setup_timer (&x, a, (unsigned long)b);

Subject: Staging: iio: Simplify return logic

This patch removes the conditional return of the ade77*_probe functions
based on the return values of iio_device_register as the latter
returns 0 or ret, the same as the checked values.

Warning found by coccinelle.

Subject: Staging: iio: use !x instead of x == NULL

Functions like devm_kzalloc, kmalloc_array, devm_ioremap,
usb_alloc_urb, alloc_netdev return NULL as a return value on failure.
Generally, When NULL represents failure, !x is commonly used.

This patch cleans up the tests on the results of these functions, thereby
using !x instead of x == NULL or NULL == x. This is done via following
coccinelle script:
@prob_7@
identifier x;
statement S;
@@

(
 x = devm_kzalloc(...);
|
 x = usb_alloc_urb(...);
|
 x = kmalloc_array(...);
|
 x = devm_ioremap(...);
|
 x = alloc_netdev(...);
)
 ...
- if(NULL == x)
+ if(!x)
        S
Further we have used isomorphism characteristics of coccinelle to
indicate x == NULL and NULL == x are equivalent. This is done via
following iso script.

Expression
@ is_null @ expression X; @@
X == NULL <=> NULL == X

Subject: Staging: rts5208: Use module_pci_driver

Macro module_pci_driver is used for drivers whose init
and exit paths does only register and unregister to pci
API. So, here remove some boilerplate code by using
module_pci_driver. Also, change driver to rtsx_driver,
to avoid implicitly redefining driver_init.

Subject: Staging: ft1000: Iterate list using list_for_each_entry

Code using doubly linked list is iterated generally  using list_empty and
list_entry functions, but it can be better written using list_for_each_entry
macro.

This patch replaces the while loop containing list_empty and list_entry with
list_for_each_entry and list_for_each_entry_safe. list_for_each_entry is a
macro which is used to iterate over a list of given type. So while loop used to
iterate over a list can be replaced with list_for_each_entry macro. However, if
list_del is used in the loop, then list_for_each_entry_safe is a better choice.
This transformation is done by using the following coccinelle script.

@ rule1 @

Subject: Staging: rtl8723au: Remove parentheses around right side an
 assignment

Parentheses are not needed around the right hand side of an assignment.
This patch remove parenthese of such occurenses. Issue was detected and
solved using the following coccinelle script:

@rule1@
identifier x, y, z;
expression E1, E2;
@@

(
x = (y == z);

x = (E1 == E2);
|
 x =
-(
...
-)
 ;
)

Subject: staging: gdm724x: use !x instead of x == NULL

Functions like devm_kzalloc, kmalloc_array, devm_ioremap,
usb_alloc_urb, alloc_netdev return NULL as a return value on failure.
Generally, When NULL represents failure, !x is commonly used.

This patch cleans up the tests on the results of these functions, thereby
using !x instead of x == NULL or NULL == x. This is done via following
coccinelle script:
@prob_7@
identifier x;
statement S;
@@

(

|
 x = kmalloc_array(...);
|
 x = devm_ioremap(...);
|
 x = alloc_netdev(...);
)
 ...
- if(NULL == x)
+ if(!x)
	S
Further we have used isomorphism characteristics of coccinelle to
indicate x == NULL and NULL == x are equivalent. This is done via
following iso script.

Subject: staging: unisys: fix some debugfs output

Subject: Staging: speakup: Add helper macro for spk_synth boilerplate

For simple modules that contain a single spk_synth without
any additional setup code then ends up being a block of
duplicated boilerplate. This patch adds a new macro,
module_spk_synth(), which replaces the
module_init()/module_exit() registrations with template
functions.

Subject: staging: vt6656: don't return zero on failure path in vt6656_probe()

If ieee80211_alloc_hw() fails in vt6656_probe(), it breaks off
initialization, but returns zero.

Subject: ion: improve ion_phys error message

Clients often get confused when ion_phys errors out due to some heap
being used that they didn't expect.  Add the heap name and heap type to
the error message to make it more obvious.

Subject: staging: panel: register reboot

we donot need the reboot notifier in module init section, as the
notifier is used after lcd is initialized. so lets register for the
reboot notifier only after we have successfully attached to the
parallel port. and similarly unregister at detach.

no need to monitor init_in_progress now as keypad_send_key() can only
be called after the timer is initialized. and timer is initialized
from keypad_init() which is in the attach section and can only execute
after the module has initialized.

Add a new header that Comedi PCI drivers can include instead of
"comedidev.h".  Currently, it just pulls in <linux/pci.h> and
"comedidev.h", but the plan is to migrate the PCI-specific stuff from
"comedidev.h" here.

Subject: staging: unisys: refactor parser_init_guts()

Fix CamelCase names:

isLocal => local
hasStandardPayloadHeader => standard_payload_header
tryAgain => retry
Away => cleanup

Fix spacing after typecasts, add missing braces to the if statement, and
eliminate the NULL comparison by just using the pointer value directly.

Subject: staging: unisys: fix placement of logical ops in visorchipset_main.c

Several if statement lines had the logical operators in the wrong place,
so fix these by moving the operator to the end of the previous line.

Subject: staging: unisys: fix CamelCase channel name ControlVm_channel

Rename the channel:

ControlVm_channel => controlvm_channel

Update all references to use the new name. Fix the odd bracketing in the
while() statement with the reference to controlvm_channel, too, so the
patch doesn't generate a warning.

Fix the CamelCase member names and that global variable:

Dumpcapture_header => dumpcapture_header
Gettextdump_header => gettextdump_header
Dumpcomplete_header => dumpcomplete_header
Gettextdump_outstanding => gettextdump_outstanding
LiveDump_info => livedump_info

Update all references and merge the definition and global structure
declaration.

From: Benjamin Romer

Subject: staging: unisys: refactor bus_create()

First, fix all CamelCase names:

busNo => bus_no
pBusInfo => bus_info
Away => cleanup

Fix the kzalloc() call so it uses the variable name rather than the
type, and update all of the references to the renamed variables and
labels.

Subject: staging: unisys: fix CamelCase in responders functions

Fix the CamelCase parameters:

busNo => bus_no
devNo => dev_no

In the functions bus_create_response(), bus_destroy_response(),
device_create_response(), device_destroy_response(), and
device_resume_response().

Fix the CamelCase global structure name

BusDev_Responders => busdev_responders

And update all references to use the corrected names.

Fix as many parenthesis alignment problems in this file as possible.

In cases where there was no good way to align to the leading parenthesis, the
content of the parenthesis were aligned as if there were no limit, and then the
leading indentation was moved back to one tab in from the previous line.

Subject: Staging: lustre: Convert macro class_export_rpc_inc into static
 inline function

This patch converts the macro class_export_rpc_inc into static inline
function. This is possible because the types of arguments at all the call
sites are same. So, the type of parameter is compatible with the types of
the arguments at all of the call sites.

Subject: staging: rtl8723au: Fix mis-placed break

In 7c3a8f2a5ec95e2b13704562f36321e20ddfc190 I made a mistake and moved
a break below a bracket, causing a situation where the for loop would
always exit when it shouldn't.

This patch corrects that mistake.

Subject: Staging: rtl8723au: Remove unused function
 rtw_atimdone_event_callback23a

This patch fixes the following sparse warning:

warning: symbol 'rtw_atimdone_event_callback23a' was not declared.
Should it be static?
rtw_atimdone_event_callback23a is local to the file rtw_mlme.c but
it isn't exposed in a header file anywhere. Moreover it is never called
from anywhere as well.

So, this patch removes this function completely.

Subject: Staging: media: remove useless dev_info to avoid null ptr dereference

Context is used in dev_info after it has been freed.
This patch fix that issue by removing the dev_info itself,
for msg doesn't look much necessary.

Subject: staging: octeon-usb: remove useless prefix from internal routines

from public ones. But in Linux all cvmx_usb routines are internal
to this driver, so such separation is useless.

Subject: staging: octeon-usb: use __BITFIELD_FIELD

Use __BITFIELD_FIELD to define bitfields. OCTEON can at least in theory
run also in little-endian mode, so the bitfield definitions should not
assume big-endian byte order.

Subject: staging: octeon-usb: try to recover from failed hardware reset

On some hardware the USB fails to initialize to sane state after
cold boot. We can detect this based on some unexpected interrupt bits,
and recover by re-initializing.

Subject: staging: dgnc: some off by one bugs

"dgnc_NumBoards" is the number of filled out elements in the
dgnc_Board[] array.  "->nasync" and "->maxports" are the same value.
They are the number of channels in the ->channels[] array so these tests
should be ">=" instead of ">" so we avoid reading past the end of the
arrays.

I cleaned up the conditions in dgnc_mgmt_ioctl() a bit.  There was a
work around for the off by one bug in the case where there were no
boards which is no longer needed.  "channel" is unsigned so it can't be
negative.

Subject: dgnc: clean up digi.h

Remove a lot of unused structs and defines from digi.h. We still have to
be careful with TIOCM_LE and TIOCMSET/TIOCMBIC because termios.h and
ioctls.h respectfully redefine them.

Subject: dgnc: get rid of dpacompat.h, move remaining stuff to digi.h

Dpacompat.h contained a lot of unused #defines and only few things are
used from it so since we've trimmed down digi.h, now we can delete
dpacompat.h and move remaining stuff into digi.h.

Subject: dgnc: use linux/types.h instead of dgnc_types.h

Dgnc_types.h unnecesarily defines TRUE as 1 and FALSE as 0 because we
already have a widely used linux/types.h so convert all TRUE to true,
FALSE to false and edit the dgnc_board struct to make sure it uses
"bool".

Subject: dgnc: remove old 2.4-2.6 compat kernel defines

dgnc_kcompat.h contains some old legacy defines in case the kernel
doesn't have __user defined but for current kernel versions these
defines don't make sense and are useless so remove them. Move the
TTY_FLIPBUF_SIZE define to digi.h because it's used in the code.

Subject: Staging: rtl8192u: Fix space issues before '(' and after ')'

Space is required before the open and after the close parenthesis.
This patch adds space after 'if' and before '{'.

This was done with the help of the following Coccinelle script:

Subject: staging: android: sync: Fix memory corruption in
 sync_timeline_signal().

The android_fence_release() function checks for active sync points
by calling list_empty() on the list head embedded on the sync
point. However, it is only valid to use list_empty() on nodes that
have been initialized with INIT_LIST_HEAD() or list_del_init().

Because the list entry has likely been removed from the active list
by sync_timeline_signal(), there is a good chance that this
WARN_ON_ONCE() will be hit due to dangling pointers pointing at
freed memory (even though the sync drivers did nothing wrong)
and memory corruption will ensue as the list entry is removed for
a second time, corrupting the active list.

This problem can be reproduced quite easily with CONFIG_DEBUG_LIST=y
and fences with more than one sync point.

Subject: staging: panel: fix lcd type

the lcd type as defined in the Kconfig is not matching in the code.
as a result the rs, rw and en pins were getting interchanged.
Kconfig defines the value of PANEL_LCD to be 1 if we select custom
configuration but in the code LCD_TYPE_CUSTOM is defined as 5.

my hardware is LCD_TYPE_CUSTOM, but the pins were assigned to it
as pins of LCD_TYPE_OLD, and it was not working.
Now values are corrected with referenece to the values defined in
Kconfig and it is working.
checked on JHD204A lcd with LCD_TYPE_CUSTOM configuration.

Subject: ft1000-pcmcia: ft1000_hw.c: fix style issues not requiring code
 refactoring

Fix all the trivial style issues (as reported by checkpatch.pl) not requiring
code refactoring. A following patch is expected to fix the remaining issues by
performing some code refactoring.

Subject: ft1000-pcmcia: ft1000_hw.c: code refactoring: add
 ft1000_read_dsp_timer()

Add new function ft1000_read_dsp_timer() replacing recurring code block for
reading DSP timer. Such code refactoring solves all remaining "line over 80
characters" warnings reported by checkpatch.pl.

Subject: staging/lustre/mdc: Handle empty but non-zero acl xattr

We have found that posix_acl_access can have a value
of \002\000\000\000.  In that case body->aclsize is
non-zero, but the there are no actuall acls stored
in the xattr.

In mdc_unpack_acl(), it only checks IS_ERR() on the
pointer returned by posix_acl_from_xattr(), it does not
check for NULL.  Because of the above situation, the
xattr aclsize can be non-zero, but posic_acl_from_xattr()
still returns NULL.  Passing NULL to posix_acl_valid()
crashes the kernel.

We add a check to properly handle the NULL return value.

Subject: staging/lustre/ptlrpc: false alarm in AT network latency measuring

If early reply of client RPC is lost and client RPC is expired and
resent, server will drop the resent RPC because it's already in
processing, server may also send reply or early reply to client,
which can still match reply buffer of the original request.
In this case, client is measuring time from resent time, but server
is reporting service time of original RPC, which is longer than
the time measured by client.

Subject: staging/lustre/mgc: detach MGC dev on error

lustre_start_mgc() creates MGC device, if error happens later on
ll_fill_super(), this device is still attached, and later mount
fails by keep complaining that the MGC device's already in the
client node.

It turns out that the device was referenced by mgc config llog data
which is arranged in the mgc lock requeue thread re-trying to get its
mgc lock, and in normal case, this llog reference only released in
mgc_blocking_ast() when the system is umount.

This patch make mgc_precleanup() to wake up requeue thread to handle
the config llog data.

This patch also makes mgc_setup() wait for mgc_requeue_thread() start
before moving on.

Subject: staging/lustre/ptlrpc: fix import state during replay

Client doesn't restore import state correctly
on reconnect during replay. It resends lock replay
when final ping was queued by server.
Server fails with "target_queue_recovery_request())

Subject: staging/lustre/llite: glimpse the inode before doing fiemap

For a new inode, the i_size is 0 until a stat, which will yield
an empty fiemap result.
Fix the issue by glimpsing the size before doing fiemap.

Subject: staging/lustre: update timestamps after buiding rpc

The mtime/atime/ctime in the write RPC has to be updated after
the RPC is built (where xid is generated), otherwise, it could
race with the setattr and updating wrong timestamps on OST side.

Seems this regression was introduced when landing clio code.

Subject: staging: sm750fb: Use memset_io instead of memset

This patch takes into account that cursor->vstart, crtc->vScreen and
share->pvMem are pointers to memory-mapped I/O and thus we should use memset_io
to make this explicit. In addition, some architectures require special treatment
of memory-mapped I/O so the previous code could actually break without this
change.

This fixes the following sparse warnings:-

Subject: staging: sm750fb: Fix __iomem pointer types

This patch annotates pointers as referring to I/O mapped memory where they ought
to be, removes now unnecessary ugly casts, eliminates an incorrect deref on I/O
mapped memory by using iowrite16 instead, and updates the pointer arithmetic
accordingly to take into account that the pointers are now byte-sized. This
fixes the following sparse warnings:-

Subject: staging: sm750fb: Remove spinlock helper function

This patch removes the unnecessary spinlock helper function and instead
calls spin_lock and spin_unlock directly.

This does *not* resolve sparse warnings about context imbalances but these are
spurious.

From ea07278681c9738b8da96670be20898cd40c7bfe Mon Sep 17 00:00:00 2001
From: Joe Perches

Subject: staging: rtl8723au: Remove uses of MAC_FMT and MAC_ARG

Use the standard vsprintf kernel extension to format
mac addresses.

This reduces object code size a bit.

Miscellanea:

o Coalesce formats
o Realign arguments
o Remove the now unused MAC_FMT and MAC_ARG #defines

Subject: staging: rtl8723au: Update RT_TRACE macro and uses

Create an rt_trace function using %pV to reduce overall code size.
Update the macro uses to remove unnecessary and now harmful parentheses.

Miscellanea around these changes:

o Coalesce formats
o Realign arguments
o Remove commented-out RT_TRACE uses
o Spelling fixes in formats
o Add missing newlines to formats
o Remove multiple newlines from formats
o Neaten formats where noticed
o Use %pM in one instance

Reduces code size ~20KB

Subject: staging: rts5208: Remove TRACE_RET and TRACE_GOTO macros

Remove these flow hiding macros.

Miscellanea:

o Add a macro and function to replace a large inline
o Simplify #includes
o Add trace.c and update Makefile
o Remove static inline filename function and use kbasename instead

This reduces object size quite a lot: ~350KB (x86-64 allyesconfig)

 506691	  83352	 115896	 705939	  ac593	drivers/staging/rts5208/built-in.o.old

Done via coccinelle script and some typing.

Subject: staging: rts5208: Remove RTSX_READ_REG and RTSX_WRITE_REG macros

Macros with hidden flow control are bad form as the code path
taken can be unexpected for the reader.

Expand these in-place and remove the macros.

Done with coccinelle script:

Subject: staging: unisys: remove redundant variable

remove the variable "registered", which was used in the cleanup() to
detect if the driver has successfully initialized. the cleanup()
is called from module_exit, so its obvious that the module has
successfully initialized. if the initialization had failed, then
we will never be in the cleanup().

we are getting dev_t as an argument in the function, so use the local

this global variable will be removed in one of the next patch of the

the dev_t was being stored in visorchipset_platform_device.dev.devt
while initializing the module. so pass that value as an argument to

Subject: tools: iio: generic_buffer: Fix generic scale extraction

When using generic_buffer to read data, the scale is not properly
detected for scale shared by type. This is caused by a problem
with the generation of generic name out of the full name.
E.g.: for current->name in_accel_z, the extracted generic name
is "in" (when it should be "in_accel"). This is used in generic_buffer
to generate scale and offset paths (in_accel_scale).

Consider the in_ or out_ prefix when extracting the generic name
from the full name.

Subject: iio: add watermark logic to iio read and poll

Currently the IIO buffer blocking read only wait until at least one
data element is available.
This patch makes the reader sleep until enough data is collected before
returning to userspace. This should limit the read() calls count when
trying to get data in batches.

From: Octavian Purdila

Subject: iio: add support for hardware fifo

Some devices have hardware buffers that can store a number of samples
for later consumption. Hardware usually provides interrupts to notify
the processor when the FIFO is full or when it has reached a certain
watermark level. This helps with reducing the number of interrupts to
the host processor and thus it helps decreasing the power consumption.

This patch enables usage of hardware FIFOs for IIO devices in
conjunction with software device buffers. When the hardware FIFO is
enabled the samples are stored in the hardware FIFO. The samples are
later flushed to the device software buffer when the number of entries
in the hardware FIFO reaches the hardware watermark or when a flush
operation is triggered by the user when doing a non-blocking read
on an empty software device buffer.

In order to implement hardware FIFO support the device drivers must
implement the following new operations: setting and getting the
hardware FIFO watermark level, flushing the hardware FIFO to the
software device buffer. The device must also expose information about
the hardware FIFO such it's minimum and maximum watermark and if
necessary a list of supported watermark values. Finally, the device
driver must activate the hardware FIFO when the device buffer is
enabled, if the current device settings allows it.

The software device buffer watermark is passed by the IIO core to the
device driver as a hint for the hardware FIFO watermark. The device
driver can adjust this value to allow for hardware limitations (such
as capping it to the maximum hardware watermark or adjust it to a
value that is supported by the hardware). It can also disable the
hardware watermark (and implicitly the hardware FIFO) it this value is
below the minimum hardware watermark.

Since a driver may support hardware FIFO only when not in triggered
buffer mode (due to different semantics of hardware FIFO sampling and
triggered sampling) this patch changes the IIO core code to allow
falling back to non-triggered buffered mode if no trigger is enabled.

Subject: iio: bmc150_accel: add support for hardware fifo

We only advertise hardware fifo support if the I2C bus supports full
I2C or smbus I2C block data reads since it is mandatory to read the
full frame in one read (otherwise the rest of the frame is discarded).

The hardware fifo is enabled only when triggers are not active because:

(a) when using the any-motion trigger the user expects to see samples
based on ROC events, but the fifo stores samples based on the sample
frequency

(b) the data-ready trigger is waking the CPU for for every sample, so
using the hardware fifo does not have any benefit

Subject: Staging: rtl8712: Use memdup_user() instead of copy_from_user()

Use memdup_user() to avoid its duplicated implementation and simplify
code. memdup_user() uses GFP_KERNEL instead of GFP_ATOMIC,
which is valid because copy_from_user() might sleep and it's useless
to make the allocation atomic. Found with coccinelle.

warning: symbol 'lstcon_console_fini' was not declared. Should it be static?
warning: symbol 'lstcon_ioctl_entry' was not declared. Should it be static?

However since these functions are used in other files,
they cannot be made static, so add protoypes for the same in console.h.

Subject: Staging: lustre: Mark internal functions as static

This patch makes functions mgc_logname2resid, mgc_set_info_async
and mgc_init static as these are only used internally.

This also eliminates sparse warnings of the type:
warning: symbol * was not declared. Should it be static?

Subject: Staging: lustre: Mark internal functions static in llog_cat.c

This patch marks functions llog_cat_set_first_idx and cat_cancel_cb
static as these are used only within this file. Also since cat_cancel_cb
is made static do not export it.

This eliminates the following sparse warning:
warning: symbol * was not declared. Should it be static?

Subject: staging: lustre: include: replace OBD_CHECK_DEV by obd_check_dev

Static inline functions are preferred over macros. Hence, the function
obd_check_dev was introduced. obd_check_dev replaces the macro
OBD_CHECK_DEV. All functions that call obd_check_dev store the return
values and return them if they represent an error code.

Some of the changes were carried out manually while others were done
using coccinelle.

Subject: staging: comedi: comedi_fops: rename comedi_set_subdevice_runflags()

`comedi_set_subdevice_runflags()` changes the comedi subdevice's
`runflags` member according to a bit-mask and new bit values.  It's name
might suggest that it only "sets", not "clears".  Rename it to
`comedi_update_subdevice_runflags()` to avoid confusion.

Subject: staging: comedi: comedi_fops: eliminate a use of subdevice spin-lock

`comedi_is_subdevice_in_error()` is only used by `comedi_read()` and
`comedi_write()` and is only called (soon) after
`comedi_is_subdevice_running()` returns `false` (with extra conditions
in the case of `comedi_write()`).  `comedi_is_subdevice_running()` and
`comedi_get_subdevice_runflags()` both call
`comedi_get_subdevice_runflags()` which uses the subdevice's spin-lock.

Eliminate one use of the subdevice's spin-lock in `comedi_read()` and
`comedi_write()` by calling `comedi_get_subdevice_runflags()` and
checking the runflags directly.  Add a couple of inline functions to
check the runflags: `comedi_is_runflags_running()` and
`comedi_is_runflags_in_error()`.  These do the same test on runflags as
`comedi_is_subdevice_running()` and `comedi_is_subdevice_in_error()` but
get passed the runflags value directly.

`comedi_is_subdevice_in_error()` is no longer used, so remove it.

Subject: staging: comedi: comedi_fops: always clear events

`comedi_event()` is called from low-level drivers to handle asynchronous
command event flags that are stored in `s->async->events` for subdevice
`s`.  It normally clears the event flags as well.  As a safety check, it
does nothing if no asynchronous command is running, but it leaves
`s->async->events` unchanged in this case.  For additional safety,
change it to always clear the event flags to avoid leaving stale event
flags set when another asynchronous command is set up.

Subject: staging: comedi: comedi_fops: send SIGIO according to command
 direction

`comedi_event()` is called from low-level drivers to handle comedi
asynchronous command event flags.  Some events cause waiting tasks to be
woken up, and a `SIGIO` signal to be sent via `kill_fasync()`.  The
signal code is `POLL_OUT` if the subdevice supports commands in the
"write" direction, or `POLL_IN` for the "read" direction.  If the
subdevice supports commands in either direction, it sends two `SIGIO`
signals, one with each code.  Change that latter case to only send one
`SIGIO` signal, using the direction of the current command to determine
the signal code.  If the `CMDF_WRITE` flag is set in the current
command, it's in the "write" direction, otherwise it's in the "read"
direction.

Subject: staging: comedi: comedi_fops: extend spin-lock scope in
 comedi_event()

`comedi_event()` is called from low-level drivers to handle comedi
asynchronous command event flags.  As a safety check, it checks the
subdevice's "run" flags to make sure an asynchronous command is running.
It can also change the run flags to mark the command as no longer
running (possibly also marking it as terminated with an error).
Checking the runflags and modifying them involves two uses of the
subdevice's spin-lock.  It seems better to do it with a single use of
the spin-lock.  This also avoids possible interactions with
`do_become_nonbusy()`.

Acquire the subdevice's spin-lock at the start of `comedi_event()` and
release it near the end, before a possible call to `kill_fasync()` (but
after it's parameter values have been determined).

Add and make use of few new inline helper functions:

* `__comedi_clear_subdevice_runflags()` -- clears some run flags without
  using the spin-lock
* `__comedi_set_subdevice_runflags()` -- sets some run flags without
  using the spin-lock
* `__comedi_get_subdevice_runflags()` -- a spin-lockless version of
  `comedi_get_subdevice_runflags()
* `__comedi_is_subdevice_running()` -- a spin-lockless version of
* `comedi_is_subdevice_running()`

Subject: staging: comedi: make comedi_internal.h self-reliant

Add `#include`s and declare incomplete types to "comedi_internal.h" so
that .c files still compile when it is the first file included.

Subject: staging: comedi: comedi_fc.h: begin migration to comedidev.h

"comedi_fc.h" contains a few inline functions used by the `do_cmdtest`
handler functions for comedi subdevices in several low-level comedi
drivers for checking asynchronous command trigger sources and arguments.
They all use the prefix `cfc_check_trigger_arg`.  Copy them over to
"../comedidev.h", but change the `cfc_` prefix to `comedi_`.  Change the
original functions in "comedi_fc.h" into simple wrappers for their
replacements.

Once the drivers have been changed to call the replacement functions,
"comedi_fc.h" can be removed.

Subject: staging: comedi: adl_pci9118: remove #include "comedi_fc.h"

As preparation for removal of "comedi_fc.h", replace calls to the
`cfc_check_trigger_...` functions from "comedi_fc.h" with the
replacement `comedi_check_trigger_...` functions from "../comedidev.h"
and remove the inclusion of "comedi_fc.h".

Subject: staging: comedi: das800: remove #include "comedi_fc.h"

As preparation for removal of "comedi_fc.h", replace calls to the
`cfc_check_trigger_...` functions from "comedi_fc.h" with the
replacement `comedi_check_trigger_...` functions from "../comedidev.h"
and remove the inclusion of "comedi_fc.h".

Subject: staging: comedi: ni_pcidio: remove #include "comedi_fc.h"

As preparation for removal of "comedi_fc.h", replace calls to the
`cfc_check_trigger_...` functions from "comedi_fc.h" with the
replacement `comedi_check_trigger_...` functions from "../comedidev.h"
and remove the inclusion of "comedi_fc.h".

Subject: staging: comedi: pcl816: remove #include "comedi_fc.h"

As preparation for removal of "comedi_fc.h", replace calls to the
`cfc_check_trigger_...` functions from "comedi_fc.h" with the
replacement `comedi_check_trigger_...` functions from "../comedidev.h"
and remove the inclusion of "comedi_fc.h".

"WARNING: please, no spaces at the start of a line",
"ERROR: code indent should use tabs where possible"
and some other small checkpatch.pl warnings and errors.

Subject: staging: sm750: fix whitespace

This patch fixes whitespace checkpatch.pl warnings and errors.
Mainly whitespaces around operators.

- ERROR: spaces required around that ':' (ctx:VxW)
- ERROR: space required after that ';' (ctx:VxV)
- ERROR: spaces required around that '<' (ctx:VxV)
- ERROR: spaces required around that '!=' (ctx:VxV)

And some small warnings around whitespace:

- ERROR: trailing whitespace
- WARNING: space prohibited before semicolon
- WARNING: unnecessary whitespace before a quoted newline

MC objects discovered during an MC bus scan were being reordered
to ensure that all allocatable objects are probed before all
non-allocatable objects. However, this is not necessary, as
drivers of non-allocatable objects, that allocate allocatable
objects in their probe function, can return -EPROBE_DEFER
if such allocations fail.

Subject: staging: fsl-mc: Refactored fsl_mc_object_allocator driver init/exit

 The fsl_mc_allocator driver does not need to be its own module
 as it is tightly integrated into the MC bus main driver. It is really
 just a sub-component of the MC bus driver. By not making fsl_mc_allocator
 its own module, we can have more control of when its initialization happens
 and we want it to happen before any driver that depends on the MC bus
 driver gets initialized.

Subject: staging: fsl-mc: Changed version matching rules for MC object drivers

Before this change, we were requiring a complete version match (major and
minor version numbers) between MC objects and corresponding drivers, to
allow MC objects to be bound to their drivers. We realized that a mismatch
in minor version numbers should be tolerated, as long as the major version
numbers match. This allows the driver to decide what to do in the minor
version mismatch case. For example, a driver may decide to run with
downgraded functionality if the MC firmware object has older minor version
number than the driver. Also, a driver with older minor version than the
MC firmware object may decide to run even though it cannot use newer
functionality of the MC object.

As part of this change, the dpmng Flib version was also updated
to match the latest MC firmware version.

Information for packet type is in ieee80211_tx_info

band IEEE80211_BAND_5GHZ for PK_TYPE_11A.

IEEE80211_TX_RC_USE_CTS_PROTECT via tx_rate flags selects PK_TYPE_11GB

This ensures that the packet is always the right type.

Subject: staging: rtl8723au: Reorganize a few functions to remove indentation

Prior to this commit, functions rtw_tkip_encrypt23a and rtw_tkip_decrypt23a had
large if blocks which contained the majority of the logic in the functions.

Rework these functions so that if the negated version of the aforementioned if
blocks' conditions are true, we return from the function with _FAIL, as
expected by the calling code.

This lets us remove two levels of indentation from the functions in
question, making them more readable.

Subject: staging: rtl8723au: Rework two byte array comparisons

Prior to this commit, rtl8723au's rtw_security.c had two instances of
byte array comparisons (for CRC checks) where the individual elements
of the byte arrays were compared one by one and an error trace would
be output if the byte arrays were determined to be different.

This commit improves the readability of the CRC verification by
placing the individual 4 bytes of each byte array into an 32-bit
unsigned integer and comparing the two resulting integers.

Thanks to Larry Finger for spotting the code style issues in the
previous version of this commit, and thanks to Joe Perches for
suggesting the use of 32-bit integer comparisons instead of byte
array comparisons.

Subject: staging: rtl8723au: Use __func__ in trace logs

Rework the trace log-related lines in rtl8723au's rtw_security.c
to use the __func__ GCC magic variable instead of hardcoding the
function names into the trace log strings. This also corrects a
copy-paste-related typo in the function named rtw_tkip_decrypt23a.

Thanks to Jes Sorensen for the suggestion to use __func__.

Subject: staging: rtl8192e: Comment cleanup (style/format)

- Multiline comments use "network subsystem comment style"
- Merge short multiline comments
- Remove empty comments
- Remove function name comment at the end of small (<1 screen) functions
- Reformat 802.11 data frame format to use spaces and network format

-In the event that fragmentation is required, the incoming payload is split into
-N parts of size ieee->fts.  The first fragment contains the SNAP header and the
-remaining packets are just data.
-
-If encryption is enabled, each fragment payload size is reduced by enough space
-to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
-So if you have 1500 bytes of payload with ieee->fts set to 500 without

-payload of each frame is reduced to 492 bytes.

Subject: Staging: rtl8192u: use correct array for debug output

This is supposed to be ->rates_ex[] instead of ->rates[].  I found this
because static checkers complain than ->rates is too small so we're
reading beyond the end of the array.  It has 12 elements instead of 15.

This bug was apparently copy and pasted from ipw2x00.  I fixed it before
in that driver 428e3cf5f98c ('ipw2x00: printing the wrong array in
debug code')
