mtk_vcodec_release_enc_pm() will be called in two places:
a. mtk_vcodec_init_enc_pm() succeed while mtk_vcodec_probe() return error.
b. mtk_vcodec_enc_remove().
In both cases put_device() call is needed, since of_find_device_by_node()
was called in mtk_vcodec_init_enc_pm() previously.
Thus add put_devices() call in mtk_vcodec_release_enc_pm()

if of_find_device_by_node() succeed, mtk_vcodec_init_enc_pm() doesn't have
a corresponding put_device(). Thus add jump target to fix the exception

If a CEC device node is unregistered, then it should be marked as
unregistered before waking up any filehandles that are waiting for
an event.
This ensures that there is no race condition where an application can
call CEC_DQEVENT and have the ioctl return 0 instead of ENODEV.

The are two instances of sizeof() being used incorrectly. The
sizeof(void *) is incorrect because urb_buffer is a char ** pointer,
fix this by using sizeof(*dev->urb_buffer). The sizeof(dma_addr_t *)
is incorrect, it should be sizeof(*dev->urb_dma), which is a dma_addr_t
and not a dma_addr_t *. This errors did not cause any issues because
it just so happens the sizes are the same.

The H.264 small buffer padding is done under
the (ctx->qsequence == 0 && payload < 512) condition.
Given this is the exact same condition immediately
above, we can move it right there, making the code

The vivid driver is a bit flaky w.r.t. the kthread timing, esp. when
running inside a virtual machine.
This is caused by calling schedule_timeout_uninterruptible(1) which can
actually take more than one jiffie. A while loop with schedule() turns out
to be a lot more precise. Also, if mutex_trylock() fails, then just call
schedule() instead of schedule_timeout_uninterruptible(1). There is no need
to wait until the next jiffer, just schedule(), then try to get the lock
again.
This is still not precise enough, it is still relatively easy to get missed
frames. This really should be converted to use a proper timer, but for now
this solves the worst problems.

The v4l2_format based ioctls can have an indirect pointer to an array
of v4l2_clip structures for overlay mode, depending on the 'type' member.
There are only five drivers that use the overlay mode and copy the
data through the __user pointer.
Change the five drivers to use memcpy() instead, and copy the data
in common code using the check_array_args() helpers. This allows
for a subsequent patch that use the same mechanism for compat
ioctl handlers.
Note that there is another pointer for a 'bitmap' that is only
used in the 'vivid' driver and nowhere else. There is no easy
way to use the same trick without adding complexity to the
common code, so this remains a __user pointer.

The ioctl commands based on v4l2_buffer have two sets of compat calls,
one for native time32 structures, and one for compat structures on
64-bit architectures.
Change the compat version to use the same approach as the other simpler
one, for both versions of the structure.
In an earlier version of the patch, I unified the v4l2_buffer_time32
and v4l2_buffer32_time32 compatibility handling into a single
implementation, but that relied on having it all in one file, rather
than having the in_compat_syscall() version in v4l2-compat-ioctl32.c.

The v4l2_ext_controls ioctl handlers use an indirect pointer to an
incompatible data structure, making the conversion particularly tricky.
Moving the compat implementation to use the new
v4l2_compat_get_user()/v4l2_compat_put_user() helpers makes it
noticeably simpler.
In v4l2_compat_get_array_args()/v4l2_compat_put_array_args(),
the 'file' argument needs to get passed to determine the
exact format, which is a bit unfortunate, as no other conversion
needs these.

The v4l2-compat-ioctl32() currently takes an extra round trip through user
space pointers when converting the data structure formats. In particular,
this involves using the compat_alloc_user_space() and copy_in_user()
helpers that often lead to worse compat handlers compared to using
in_compat_syscall() checks when copying the data.
The native implementation already gained a simpler method to deal with
the conversion for the time32 conversion. Hook into the same places to
provide a location for reading and writing user space data from inside
of the generic video_usercopy() helper.
Hans Verkuil rewrote the video_get_user() function here to simplify
the zeroing of the extra input fields and fixed a couple of bugs in
the original implementation.

Pull drm updates from Dave Airlie:
"Not a major amount of change, the i915 trees got split into display
and gt trees to better facilitate higher level review, and there's a
major refactoring of i915 GEM locking to use more core kernel concepts
(like ww-mutexes). msm gets per-process pagetables, older AMD SI cards
get DC support, nouveau got a bump in displayport support with common
code extraction from i915.
Outside of drm this contains a couple of patches for hexint
moduleparams which you've acked, and a virtio common code tree that
you should also get via it's regular path.

- Cadence MHDP8546 DisplayPort bridge driver
core:
- cross-driver scatterlist cleanups

drxk_hard.c: In function 'hi_command.constprop':
drxk_hard.c:1016:5: warning: 'wait_cmd' may be used uninitialized in this function [-Wmaybe-uninitialized]
1015 | } while ((status < 0) && (retry_count < DRXK_MAX_RETRIES)
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1016 | && (wait_cmd != 0));
| ^~~~~~~~~~~~~~~~~~
The underlying cause is that the while condition is wrong. It should be:
(status < 0 || wait_cmd) && (retry_count < DRXK_MAX_RETRIES)
'wait_cmd' is only valid if '!(status < 0)'.

struct s5k5baf_fw ends with this:
struct {
u16 id;
u16 offset;
} seq[0];
u16 data[];
};
which is rather confusing and can cause gcc warnings:
s5k5baf.c: In function 's5k5baf_load_setfile.isra':
s5k5baf.c:390:13: warning: array subscript 65535 is outside the bounds of an interior zero-length array 'struct <anonymous>[0]' [-Wzero-length-bounds]
390 | if (f->seq[i].offset + d <= end)
| ~~~~~~^~~
It turns out that 'data[]' is used in only one place and it can
easily be replaced by &fw->seq[0].id and 'seq[0]' can be replaced by
'seq[]'.
This is both more readable and solved that warnings.

pixelformat in vin priv structure holds V4L2_PIX_FMT_* and not
MEDIA_BUS_FMT_* so make sure we check against V4L2_PIX_FMT_* formats
while setting the VNIS_REG.
