473e4b4c1c media: stv0288: get rid of set_property boilerplate
This driver doesn't implement support for set_property(). Yet,
it implements a boilerplate for it. Get rid of it.

Previously, with crop (0, 0), (4255, 3167), VTS < 0xC9E was resulting in
blank frames sometimes. This appeared as video flickering. But we need VTS
< 0xC9E to get ~30fps.

Omni Vision recommends to use crop (0,8), (4255, 3159) for 4224x3136. With
this crop, VTS 0xC8E is supported and yields ~30fps.

cecfe9b8a5 [media] v4l2-ctrls.c: allow empty control handlers
If you have a control handler that does not contain any controls, then
currently calling VIDIOC_G/S/TRY_EXT_CTRLS with count == 0 will return
-EINVAL in the class_check() function.

This is not correct, there is no reason why this should return an error.

The purpose of setting count to 0 is to test if the ioctl can mix controls
from different control classes. And this is possible. The fact that there
are not actually any controls defined is another matter that is unrelated
to this test.

This caused v4l2-compliance to fail, so that is fixed with this patch applied.

5dfbf6c51c [media] rcar_drif: fix potential uninitialized variable use
Older compilers like gcc-4.6 may run into a case that returns
an uninitialized variable from rcar_drif_enable_rx() if that
function was ever called with an empty cur_ch_mask:

drivers/media/platform/rcar_drif.c:658:2: error: ‘ret’ may be used uninitialized in this function [-Werror=uninitialized]

Newer compilers don't have that problem as they optimize the
'ret' variable away and just return zero in that case.

This changes the function to return -EINVAL for this particular
failure, to make it consistent across all compiler versions.
In case gcc gets changed to report a warning for it in the
future, it's also a good idea to shut it up now.

1a2a60b1af [media] media: rc: gpio-ir-recv: use devm_request_irq
Use of devm_request_irq simplifies error unwinding and as
free_irq was the last user of driver remove function,
remove it too.

375929f9f4 [media] media: rc: gpio-ir-recv: do not allow threaded interrupt handler

interrupt handler is run at too unpredictable time which turns
timing information wrong. Fix it by requesting regular interrupt.
