[ Upstream commit 61334819aca018c3416ee6c330a08a49c1524fc3 ]
s3c_camif_register_video_node() works with video_device structure stored
as a field of camif_vp, so it should not be kfreed.
But there is video_device_release() on error path that do it.

[ Upstream commit 0aeccc63f3bc4cfd49dc4893da1409402ee6b295 ]
The driver uses the upper-bound approach to decide the target JPEG
encode quality, but there's a logic bug that if the desired quality is
higher than what the driver can support, the driver falls back to using
the worst quality.
Fix the bug by assuming using the best quality in the beginning, and
with trivial refactor to avoid long lines.

[ Upstream commit bd5b50b329e850d467e7bcc07b2b6bde3752fbda ]
There may be some a race condition between timer function
bttv_irq_timeout and bttv_remove. The timer is setup in
probe and there is no timer_delete operation in remove
function. When it hit kfree btv, the function might still be
invoked, which will cause use after free bug.
This bug is found by static analysis, it may be false positive.
Fix it by adding del_timer_sync invoking to the remove function.

[ Upstream commit eeaa47d182fedfe68b8fd40ef3798761c8904791 ]
The ov5640_update_pixel_rate() function handles the parallel and MIPI
CSI-2 cases separately.
When running on a parallel setup the V4L2_CID_PIXEL_RATE value is
calculated at the beginning of the function using the values configured
with the frame_interval operations, and then the function immediately
returns.
The remaining of the function handles the MIPI CSI-2 configuration and
should not use the 'current_fr' and 'def_fps' fields as those are only
relevant for parallel mode.
Drop a small section of dead code that updates vblank using
frame_interval on a MIPI CSI-2 setup.

[ Upstream commit 6e481d52d363218a3e6feb31694da74b38b30fad ]
In case of encoded input VP9 data width that is not multiple of macroblock
size, which is 16 (e.g. 1080x1920 frames, where 1080 is multiple of 8), the
width is padded to be a multiple of macroblock size (for 1080x1920 frames,
that is 1088x1920).
The hantro_postproc_g2_enable() checks whether the encoded data width is
equal to decoded frame width, and if not, enables down-scale mode. For a
frame where input is 1080x1920 and output is 1088x1920, this is incorrect
as no down-scale happens, the frame is only padded. Enabling the down-scale
mode in this case results in corrupted frames.
Fix this by adjusting the check to test whether encoded data width is
greater than decoded frame width, and only in that case enable the
down-scale mode.
To generate input test data to trigger this bug, use e.g.:
$ gst-launch-1.0 videotestsrc ! video/x-raw,width=272,height=256,format=I420 ! \
vp9enc ! matroskamux ! filesink location=/tmp/test.vp9
To trigger the bug upon decoding (note that the NV12 must be forced, as
that assures the output data would pass the G2 postproc):
$ gst-launch-1.0 filesrc location=/tmp/test.vp9 ! matroskademux ! vp9parse ! \
v4l2slvp9dec ! video/x-raw,format=NV12 ! videoconvert ! fbdevsink

[ Upstream commit 99e1241049a92dd3e9a90a0f91e32ce390133278 ]
Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically.
Therefore, it needs to be freed, which is done by the driver core for
us once all references to the device are gone. Therefore, move the
dev_set_name() call immediately before the call device_register(), which
either succeeds (then the freeing will be done upon subsequent remvoal),
or puts the reference in the error call. Also, it is not unusual that the
return value of dev_set_name is not checked.

[ Upstream commit 402ab979b29126068e0b596b641422ff7490214c ]
As the comment of device_register() says, it should use put_device()
to give up the reference in the error path. Then, insofar resources
will be freed in pcmcia_release_dev(), the error path is no longer
needed. In particular, this means that the (previously missing) dropping
of the reference to &p_dev->function_config->ref is now handled by
pcmcia_release_dev().

[ Upstream commit e3ea1b4847e49234e691c0d66bf030bd65bb7f2b ]
If device_register() returns error in pccardd(), it leads two issues:
1. The socket_released has never been completed, it will block
pcmcia_unregister_socket(), because of waiting for completion
of socket_released.
2. The device name allocated by dev_set_name() is leaked.
Fix this two issues by calling put_device() when device_register() fails.
socket_released can be completed in pcmcia_release_socket(), the name can
be freed in kobject_cleanup().

[ Upstream commit 2be36c09b6b07306be33519e1aa70d2e2a2161bb ]
The current implementation passes PIN_IO_INTA_OUT (2) as a mask and
PIN_IO_INTAPM (GENMASK(1, 0)) as a value.
Swap the variables to assign mask and value the right way.
This error was first introduced with the alarm support. For better or
worse it worked as expected because 0x02 was applied as a mask to 0x03,
resulting 0x02 anyway. This will of course not work for any other value.

[ Upstream commit 0144e3b85d7b42e8a4cda991c0e81f131897457a ]
The GHCB specification declares that the firmware error value for
a guest request will be stored in the lower 32 bits of EXIT_INFO_2. The
upper 32 bits are for the VMM's own error code. The fw_err argument to
snp_guest_issue_request() is thus a misnomer, and callers will need
access to all 64 bits.
The type of unsigned long also causes problems, since sw_exit_info2 is
u64 (unsigned long long) vs the argument's unsigned long*. Change this
type for issuing the guest request. Pass the ioctl command struct's error
field directly instead of in a local variable, since an incomplete guest
request may not set the error code, and uninitialized stack memory would
be written back to user space.
The firmware might not even be called, so bookend the call with the no
firmware call error and clear the error.
Since the "fw_err" field is really exitinfo2 split into the upper bits'
vmm error code and lower bits' firmware error code, convert the 64 bit
value to a union.

[ Upstream commit a5f928db59519a15e82ecba4ae3e7cbf5a44715a ]
If this driver enables the xHC clocks while resuming from sleep, it calls
clk_prepare_enable() without checking for errors and blithely goes on to
read/write the xHC's registers -- which, with the xHC not being clocked,
at least on ARM32 usually causes an imprecise external abort exceptions
which cause kernel oops. Currently, the chips for which the driver does
the clock dance on suspend/resume seem to be the Broadcom STB SoCs, based
on ARM32 CPUs, as it seems...
Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.

The AMD USB host controller (1022:43f7) isn't going into PCI D3 by default
without anything connected. This is because the policy that was introduced
by commit a611bf473d1f ("xhci-pci: Set runtime PM as default policy on all
xHC 1.2 or later devices") only covered 1.2 or later.
The 1.1 specification also has the same requirement as the 1.2
specification for D3 support. So expand the runtime PM as default policy
to all AMD 1.1 devices as well.

[ Upstream commit 73b25505ce043b561028e5571d84dc82aa53c2b4 ]
The VAS open window call prints error message and returns -EBUSY
after the migration suspend event initiated and until the resume
event completed on the destination system. It can cause the log
buffer filled with these error messages if the user space issues
continuous open window calls. Similar case even for DLPAR CPU
remove event when no credits are available until the credits are
freed or with the other DLPAR CPU add event.
So changes in the patch to use pr_err_ratelimited() instead of
pr_err() to display open window failure and not-available credits
error messages.
Use pr_fmt() and make the corresponding changes to have the
consistencein prefix all pr_*() messages (vas-api.c).

When MODULE_DEVICE_TABLE(ishtp, ) is built on a host with a different
endianness from the target architecture, it results in an incorrect
MODULE_ALIAS().
For example, see a case where drivers/platform/x86/intel/ishtp_eclite.c
is built as a module for x86.
If you build it on a little-endian host, you will get the correct
MODULE_ALIAS:
$ grep MODULE_ALIAS drivers/platform/x86/intel/ishtp_eclite.mod.c
MODULE_ALIAS("ishtp:{6A19CC4B-D760-4DE3-B14D-F25EBD0FBCD9}");
However, if you build it on a big-endian host, you will get a wrong
MODULE_ALIAS:
$ grep MODULE_ALIAS drivers/platform/x86/intel/ishtp_eclite.mod.c
MODULE_ALIAS("ishtp:{BD0FBCD9-F25E-B14D-4DE3-D7606A19CC4B}");
This issue has been unnoticed because the x86 kernel is most likely built
natively on an x86 host.

When MODULE_DEVICE_TABLE(tee, ) is built on a host with a different

For example, see a case where drivers/char/hw_random/optee-rng.c

If you build it on a little-endian host, you will get the correct

The same problem also occurs when you enable CONFIG_CPU_BIG_ENDIAN,
and build it on a little-endian host.
This issue has been unnoticed because the ARM kernel is configured for
little-endian by default, and most likely built on a little-endian host
(cross-build on x86 or native-build on ARM).

sw_desc->nb_desc is zero.
In such a case pxad_free_desc() is called and it will BUG_ON().
Remove this erroneous BUG_ON().
It is also useless, because if "sw_desc->nb_desc == 0", then, on the first
iteration of the for loop, i is -1 and the loop will not be executed.
(both i and sw_desc->nb_desc are 'int')
