71ecc5356d sun4i-csi: drop read/write, enable VB2_DMABUF
For no obvious reason VB2_DMABUF was not enabled. Add this.

Also both read and write file ops were set, but this was not enabled
in the vb2 io_modes or in the device_caps capabilities. Drop this.

a69a7a3326 v4l2-core: Print control name in VIDIOC_S/G_(EXT)_CTRL(S)
While debugging, it's currently really hard to identify controls
by their ID. Print the control name making the print more helpful.

With this change, the print changes from:

video1: VIDIOC_S_EXT_CTRLS: which=0xf010000, count=5, error_idx=4, request_fd=45, id/size=0x990ce8/1048, id/size=0x990ce9/12, id/size=0x990cea/480, id/size=0x990ceb/896, id/size=0x990cec/400

video1: VIDIOC_S_EXT_CTRLS: which=0xf010000, count=5, error_idx=4, request_fd=42, name=H264 Sequence Parameter Set, id/size=0x990ce8/1048, name=H264 Picture Parameter Set, id/size=0x990ce9/12, name=H264 Scaling Matrix, id/size=0x990cea/480, name=H264 Slice Parameters, id/size=0x990ceb/896, name=H264 Decode Parameters, id/size=0x990cec/400

For instance, this is specially helpful when the ioctl fails. Consider
the following example:

v4l2-ctrls: prepare_ext_ctrls: video1: pointer control id 0x990cec size too small, 400 bytes but 784 bytes needed
v4l2-ctrls: try_set_ext_ctrls: video1: video1: try_set_ext_ctrls_common failed (-14)
video1: VIDIOC_S_EXT_CTRLS: error -14: which=0xf010000, count=5, error_idx=5, request_fd=39, name=H264 Sequence Parameter Set, id/size=0x990ce8/1048, name=H264 Picture Parameter Set, id/size=0x990ce9/12, name=H264 Scaling Matrix, id/size=0x990cea/480, name=H264 Slice Parameters, id/size=0x990ceb/896, name=H264 Decode Parameters, id/size=0x990cec/400

6f01dfb760 media: cros-ec-cec: do not bail on device_init_wakeup failure
Do not fail probing when device_init_wakeup fails.

device_init_wakeup fails when the device is already enabled as wakeup
device. Hence, the driver fails to probe the device if:
- The device has already been enabled for wakeup (by e.g. sysfs)
- The driver has been unloaded and is being loaded again.

This goal of the patch is to fix the above cases.

Overwhelming majority of the drivers do not check device_init_wakeup
return code.

0f879bab72 media: rockchip: rga: Only set output CSC mode for RGB input
Setting the output CSC mode is required for a YUV output, but must not
be set when the input is also YUV. Doing this (as tested with a YUV420P
to YUV420P conversion) results in wrong colors.

Adapt the logic to only set the output CSC mode when the output is YUV and
the input is RGB. Also add a comment to clarify the rationale.

ded874ece2 media: rockchip: rga: Introduce color fmt macros and refactor CSC mode logic
This introduces two macros: RGA_COLOR_FMT_IS_YUV and RGA_COLOR_FMT_IS_RGB

These macros are then used to refactor the logic for CSC mode selection.
The two nested tests for input colorspace are simplified into a single one,
with a logical and, making the whole more readable.

Fix up inconsistent usage of upper and lowercase letters in "Samsung"

"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names.  Therefore they should be written with lowercase letters starting
with capital letter.

The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.

Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on

0d1e342a17 media: mtk-mdp: Remove states for format checks
The mtk-mdp driver uses states to check if the formats have been set
on the capture and output when turning the streaming on, setting
controls or setting the selection rectangles.
Those states are reset when 0 buffers are requested like when checking
capabilities.
This patch removes all format checks and set one by default as queues in
V4L2 are expected to always have a format set.

If fw_csr_string() returns -ENOENT, then "name" is uninitialized.  So
then the "strlen(model_names[i]) <= name_len" is true because strlen()
is unsigned and -ENOENT is type promoted to a very high positive value.
Then the "strncmp(name, model_names[i], name_len)" uses uninitialized
data because "name" is uninitialized.

7cd08d6eed media: usb: pwc: pwc.h: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

as MEDIA_ENT_F_IO_V4L implies V4L2 video node.

fit from the functions defined in include/uapi/linux/media.h.

What led to this crash was an injected memory allocation failure in
media_request_alloc():

When that allocation fails, filp->private_data is left uninitialized
which media_request_close() does not expect and crashes.

To avoid this, reorder media_request_alloc() such that
allocating the struct file happens as the last step thus
media_request_close() will no longer get called for a partially created
media request.
