384e83db20 media: camif-core: Do not check for 0 return after calling platform_get_irq()
It is not possible for platform_get_irq() to return 0. Use the
return value from platform_get_irq().

f7692d1d0a media: jpeg-core: Remove redundant dev_err()
There is no need to call the dev_err() function directly to print a custom
message when handling an error from platform_get_irq() function as
it is going to display an appropriate error message in case of a failure.

b8ec754ae4 media: v4l: async: Set v4l2_device and subdev in async notifier init
Set the v4l2_device already in async notifier init, so struct device
related to it will be available before the notifier is registered. This
requires separating notifier initialisation into two functions, one that
takes v4l2_device as its argument, v4l2_async_nf_init and
v4l2_async_subdev_nf_init, for sub-device notifiers. Registering the
notifier will use a single function, v4l2_async_nf_register.

This is done in order to make struct device available earlier, during
construction of the async connections, for sensible debug prints.

adb2dcd5f2 media: v4l: async: Rename v4l2_async_subdev as v4l2_async_connection
Rename v4l2_async_subdev as v4l2_async_connection, in order to
differentiate between the sub-devices and their connections: one
sub-device can have many connections but the V4L2 async framework has so
far allowed just a single one. Connections in this context will later
translate into either MC ancillary or data links.

This patch prepares changing that relation by changing existing users of
v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices
themselves will not be needed anymore

Additionally, __v4l2_async_nf_add_subdev() has been renamed
__v4l2_async_nf_add_connection().

7c7e33b799 media: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

72a6127e93 media: Add common header file with JPEG marker definitions
When compile-testing on mips/RB532 with W=1:

    arch/mips/include/asm/mach-rc32434/rb.h:13: note: this is the location of the previous definition
       13 | #define RST  (1 << 15)
	  |
    drivers/media/platform/mediatek/jpeg/mtk_jpeg_dec_parse.c:15: warning: "RST" redefined
       15 | #define RST 0xd0
	  |
    drivers/media/platform/renesas/rcar_jpu.c:77: warning: "RST" redefined
       77 | #define RST 0xd0
	  |

"RST" is indeed a name too short to be conflict-free.

Fix this by creating a common <media/jpeg.h> header file, containing
definitions for all JPEG markers used, prefixed by "JPEG_MARKER_", based
on the existing private definitions in the Samsung S5P JPEG driver, and
convert all affected drivers.

e3a69496a1 media: Prefer designated initializers over memset for subdev pad ops
Structures passed to subdev pad operations are all zero-initialized, but
not always with the same kind of code constructs. While most drivers
used designated initializers, which zero all the fields that are not
specified, when declaring variables, some use memset(). Those two
methods lead to the same end result, and, depending on compiler
optimizations, may even be completely equivalent, but they're not
consistent.

Improve coding style consistency by using designated initializers
instead of calling memset(). Where applicable, also move the variables
to inner scopes of for loops to ensure correct initialization in all
iterations.

ecefa105cc media: Zero-initialize all structures passed to subdev pad operations
Several drivers call subdev pad operations, passing structures that are
not fully zeroed. While the drivers initialize the fields they care
about explicitly, this results in reserved fields having uninitialized
values. Future kernel API changes that make use of those fields thus
risk breaking proper driver operation in ways that could be hard to
detect.

To avoid this, make the code more robust by zero-initializing all the
structures passed to subdev pad operation. Maintain a consistent coding
style by preferring designated initializers (which zero-initialize all
the fields that are not specified) over memset() where possible, and
make variable declarations local to inner scopes where applicable. One
notable exception to this rule is in the ipu3 driver, where a memset()
is needed as the structure is not a local variable but a function
parameter provided by the caller.

Not all fields of those structures can be initialized when declaring the
variables, as the values for those fields are computed later in the
code. Initialize the 'which' field in all cases, and other fields when
the variable declaration is so close to the v4l2_subdev_call() call that
it keeps all the context easily visible when reading the code, to avoid
hindering readability.

Pull media updates from Mauro Carvalho Chehab:

 - Removal of several VB1-only deprecated drivers: cpia2, fsl-viu, meye,
   stkwebcam, tm6000, vpfe_capture and zr364xx

 - saa7146 recovered from staging/deprecated. We opted to give ti a
   chance, and, instead of deprecating it, the intention is to write
   patches migrating it from VB1 to VB2.

 - av7110 returned from staging/deprecated/ to staging/ as we're not
   planning on dropping it any time soon

 - media controller API has gained experimental support for G_ROUTING
   and streams API. No drivers use it right now. We're planning to add
   one after -rc1, giving some time to experience the API and eventually
   have changes during the next development cycle

 - New sensor drivers: imx296, imx415, ov8858

 - Atomisp had lots of changes, specially on its sensor's interface,
   making atomisp sensor drivers closer to normal sensor drivers

 - media controller kAPI has gained some helpers to traverse pipelines

 - uvcvideo now better support power line control

 - lots of bug fixes, cleanups and driver improvements

d8a46bc4e1 media: s5p-mfc: Fix to handle reference queue during finishing
On receiving last buffer driver puts MFC to MFCINST_FINISHING state which
in turn skips transferring of frame from SRC to REF queue. This causes
driver to stop MFC encoding and last frame is lost.

This patch guarantees safe handling of frames during MFCINST_FINISHING and
correct clearing of workbit to avoid early stopping of encoding.

48ecee6159 media: platform: exynos4-is: Fix error handling in fimc_md_init()
A problem about modprobe s5p_fimc failed is triggered with the
following log given:

 [  272.075275] Error: Driver 'exynos4-fimc' is already registered, aborting...
 modprobe: ERROR: could not insert 's5p_fimc': Device or resource busy

The reason is that fimc_md_init() returns platform_driver_register()
directly without checking its return value, if platform_driver_register()
failed, it returns without unregister fimc_driver, resulting the
s5p_fimc can never be installed later.
A simple call graph is shown as below:

 fimc_md_init()
   fimc_register_driver() # register fimc_driver
   platform_driver_register()
     platform_driver_register()
       driver_register()
         bus_add_driver()
           dev = kzalloc(...) # OOM happened
   # return without unregister fimc_driver

Fix by unregister fimc_driver when platform_driver_register() returns
error.

Commit 1f391df446 ("media: v4l2-async: Use endpoints in
__v4l2_async_nf_add_fwnode_remote()") changed the data that is stored in
the v4l2_async_subdev internals from the fwnode pointer to the parent
device to the fwnode pointer to the matched endpoint. This broke the
sensor matching code, which relied on the particular fwnode data in the
v4l2_async_subdev internals. Fix this by simply matching the
v4l2_async_subdev pointer, which is already available there.
