clk_prepare_enable() may fail, so we should better check its return value and propagate it in the case of error. Signed-off-by:

devm_clk_get() may return different error codes other than -EPROBE_DEFER, so it is better to return the real error code instead. Signed-off-by:

Previously, images were relatively darker due to non-optimal settings for black target level and bias. Now, use recommended settings for black target level and output bias as default values. The same default settings apply to all the resolutions. Given these recommeneded settings do not change dynamically, add these to existing mode register settings. Signed-off-by:

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. Signed-off-by:

Make sure to check that we actually have an Interface Association Descriptor before dereferencing it during probe to avoid dereferencing a NULL-pointer. Fixes: e0d3bafd ("V4L/DVB (10954): Add cx231xx USB driver") Cc: stable <stable@vger.kernel.org> # 2.6.30 Reported-by:

This converts to use setup_timer() to set callback and data, though it doesn't look like this would have worked with timer checking enabled since no init_timer() was ever called before. Cc: Mats Randgaard <matrandg@cisco.com> Cc: Mauro Carvalho Chehab <mchehab@kernel.org> Signed-off-by:

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. Link: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82203Signed-off-by:

Make these const as they are not modified in the file referencing them. They are only used when their function pointer fields invokes a function and therefore none of the structure fields are getting modified. Also, add a const to the declaration in the header. Signed-off-by:
