Subject: fujitsu-laptop: Clear build warnings

When CONFIG_FUJITSU_LAPTOP_DEBUG is disabled and W=1, the
fujitsu-laptop driver builds with the following warnings:

drivers/platform/x86/fujitsu-laptop.c: In function "bl_update_status":
drivers/platform/x86/fujitsu-laptop.c:409:8: warning: suggest braces around empty body in an "if" statement [-Wempty-body]

drivers/platform/x86/fujitsu-laptop.c:418:8: warning: suggest braces around empty body in an "if" statement [-Wempty-body]
    ret);
        ^

Rework the debug printk helper macro to get rid of these. I verified
that this change has no effect on the generated binary, both in the
debug and non-debug case.

The _set and _get arguments to the EEEPC_CREATE_SENSOR_ATTR() macro

Drop the trailing semicolon from that macro, while we're at it.

Subject: thinkpad_acpi: Update mapping for F12 hotkey on *40 models to
 KEY_FILE

The new keyboard found on the *40 models is also being sold as a standalone
keyboard (with trackpoint):
http://shop.lenovo.com/us/en/itemdetails/0B47189/460/60AC6A0372B14F5BA7B12F1FF88E33C7

This uses a standard HUT code for the F12 key with the 6 square boxes on it,
which gets mapped to KEY_FILE by the kernel. Change the mapping done of
identical laptop key done by thinkpad_acpi to also send KEY_FILE for
consistency.

Subject: ideapad-laptop: Change Lenovo Yoga 2 series rfkill handling

It seems that the same problems which lead to adding an rfkill blacklist and
putting the Lenovo Yoga 2 11 on it are also present on the Lenovo Yoga 2 13
and Lenovo Yoga 2 Pro too:
https://bugzilla.redhat.com/show_bug.cgi?id=1021036
https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612

Testing has shown that the firmware rfkill settings are persistent over
reboots. So blacklisting the driver is not good enough, if the wifi is blocked
at the firmware level the wifi needs to be explictly unblocked through the
ideapad-laptop interface.

And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices
with hardware kill switch reports the hardware switch state, needs to be
explictly set to 1 (radio enabled / not blocked).

So this patch does 3 things to get proper rfkill handling on these models:

1) Instead of blacklisting the rfkill functionality, which means that people
with a firmware blocked wifi get stuck in that situation, ignore the value
reported by the not present hardware rfkill switch, as this is what is causing
ideapad-laptop to wrongly report all radios as hardware blocks. But do register
the rfkill interfaces so that the user can soft [un]block them.

2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1

3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2
series is affected.

Subject: asus-wmi: backlight_init: Stop treating -ENODEV as if its not an
 error

When bl_power support got added to asus-wmi, the error handling for it was
written to ignore -ENODEV, to avoid not registering a backlight interface for
models which have no bl_power control, but do have brightness control.

At the same time the error handling for brightness_max was modified to do the
same, this is wrong, when there is no brightness_max asus-wmi should not
register a backlight interface.

Note the caller of asus_wmi_backlight_init already special cases -ENODEV,
and will not cause the wmi driver regristration to fail because of a
-ENODEV return from asus_wmi_backlight_init.

control the wifi and wifi-led status.
But, it'll lead to bt status error if asus-wmi driver controls bt as well.
So, for X200CA, asus-wmi driver controls wifi status only and have to set
wapf to 1.

Subject: WMI: Remove unnecessary null test

This patch removes the null test on block. block is initialized at the
beginning of the function to &wblock->gblock. Since wblock is
dereferenced prior to the null test, wblock must be a valid pointer,
and &wblock->gblock cannot be null.

The following Coccinelle script is used for detecting the change:

@r@
expression e,f;
identifier g,y;
statement S1,S2;
@@

*e = &f->g
<+...
 f->y
 ...+>
*if (e != NULL || ...)

Quite a lot of code and data of acer-wmi.c is only ever used during
initialization. Mark those accordingly -- and constify, where
appropriate -- so the memory can be released afterwards.

All in all those changes move ~10 kB of code and data to the .init
sections, marking them for release after initialization has finished.

Subject: dell-laptop: Mark dell_quirks[] DMI table as __initconst

The dell_quirks[] DMI table is only ever used during initialization.
Mark it as __initconst so its memory can be released afterwards --
roughly 5.7 kB. In turn, the callback function can be marked with
__init, too.

Also the touchpad_led_init() function can be marked __init as it's only
referenced from dell_init() -- an __init function.

Subject: fujitsu-tablet: Mark DMI callbacks as __init code

The DMI table is already marked as __initconst, so can be the callback
functions as they're only used in that context.

Subject: fujitsu-laptop: Mark fujitsu_dmi_table[] DMI table as __initconst

The DMI table is only ever used during initialization. Mark it as
__initconst so its memory can be released afterwards -- roughly 1.5 kB.
In turn, the callback functions can be marked with __init, too.

Subject: toshiba_acpi: Add extra check to backlight code

Some Toshiba models (most notably Qosmios) come with an
incomplete backlight method where the AML code doesn't
check for write or read commands and always returns
HCI_SUCCESS and the actual brightness (and in some
cases the max brightness), thus allowing the backlight
interface to be registered without write support.

This patch changes the set_lcd_brightness function,
checking the returned values for values greater than
zero to avoid registering a broken backlight interface.

Subject: toshiba_acpi: Add Qosmio X75-A to the alt keymap dmi list

The Toshiba Qosmio X75-A series models also come with
the new keymap layout.

This patch adds this model to the alt_keymap_dmi list,
along with an extra key found on these models.

Subject: compal-laptop: correct invalid hwmon name

Change the name of the hwmon interface from "compal-laptop" to "compal".
A dash is an invalid character for a hwmon name and caused the call to
hwmon_device_register_with_groups() to fail.

The actual x401u does not use the so named x401u quirk but the x55u quirk.
All that the x401u quirk does it setting wapf to 4, so rename it to wapf4 to
stop the confusion.

Subject: platform/x86: Toshiba HDD Active Protection Sensor

This driver adds support for the built-in accelereometer found
on recent Toshiba laptops with HID TOS620A.

This driver receives ACPI notify events 0x80 when the sensor
detects a sudden move or a harsh vibration, as well as an
ACPI notify event 0x81 whenever the movement or vibration has
been stabilized.

Also provides sysfs entries to get/set the desired protection
level and reseting the HDD protection interface.
