media: remove conditional return with no effect

2026-07-28T13:17:55+00:00

Both branches of the check return the same value, so the check has
no effect. Remove it and return the value directly.

This is the result of running the Coccinelle script from
scripts/coccinelle/misc/cond_return_no_effect.cocci.

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of  by the more specific
 where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

media: platform: drop vb2_ops_wait_prepare/finish

2024-10-28T08:20:07+00:00

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish
are NULL") it is no longer needed to set the wait_prepare/finish
vb2_ops callbacks as long as the lock field in vb2_queue is set.

Since the vb2_ops_wait_prepare/finish callbacks already rely on that field,
we can safely drop these callbacks.

This simplifies the code and this is a step towards the goal of deleting
these callbacks.

media: Switch back to struct platform_driver::remove()

2024-10-12T14:28:25+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/media to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

media: microchip-isc: Drop v4l2_subdev_link_validate() for video devices

2024-08-26T13:36:11+00:00

The v4l2_subdev_link_validate() function is a helper designed to
validate links whose sink is a subdev. When called on a link whose sink
is a video device, it only prints a warning and returns. As the
microchip-isc driver implements manual validate of the subdev to video
device link, we can just drop the v4l2_subdev_link_validate() to avoid
the warning.

media: microchip-isc: Remove dead code in pipeline validation

2023-12-04T10:21:46+00:00

The isc_try_fse() function, called from isc_validate(), takes two
parameters, an isc_device pointer, and a v4l2_subdev_state pointer. The
isc_device is accessed but not modified by the function. The state is
modified, including the struct v4l2_subdev_pad_config array it points
to, but they are then never used by the caller. Furthermore, the V4L2
subdev operation called by isc_try_fse() doesn't modify the subdev it is
called on. The isc_try_fse() function has thus no effect, and can just
be dropped.

media: v4l2-subdev: Rename .init_cfg() operation to .init_state()

2023-12-04T09:37:47+00:00

The subdev .init_cfg() operation is affected by two issues:

- It has long been extended to initialize a whole v4l2_subdev_state
  instead of just a v4l2_subdev_pad_config, but its name has stuck
  around.

- Despite operating on a whole subdev state and not being directly
  exposed to the subdev users (either in-kernel or through the userspace
  API), .init_cfg() is categorized as a subdev pad operation.

This participates in making the subdev API confusing for new developers.
Fix it by renaming the operation to .init_state(), and make it a subdev
internal operation.
