There are no users of this functionality (ir-lirc-codec.c has its own implementation and lirc_zilog.c doesn't use it) so remove it. This only affects users of the lirc kapi, not rc-core drivers. Signed-off-by:

The 0-day robot reports: drivers/media/rc/gpio-ir-recv.c: In function 'gpio_ir_recv_irq': >> drivers/media/rc/gpio-ir-recv.c:38:8: error: implicit declaration of function 'gpiod_get_value' [-Werror=implicit-function-declaration] Fixes: eed008e6 ("[media] media: rc: gpio-ir-recv: use gpiolib API") For some reason only partial patch was applied. Also include gpio/consumer.h otherwise compile test fails. Reported-by:

The clock control is not explicitly controlled by the driver in two cases: ACPI based systems and when the clock is part of the power sequence of the camera module. Signed-off-by:

Obtain the clock rate from the clock framework if it's not available through DT. The assumption is that the parent device (camera module) defines the rate as clock control is a part of the power on and power off sequences --- which are camera module specific. Also use the clock rate from DT if no clock is provided. Signed-off-by:

The external clock frequency was set by the driver but the obtained frequency was never verified. Do that. Being able to obtain the exact frequency is important as the value is used for PLL calculations which may result in frequencies that violate the PLL tree limits. Signed-off-by:

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. 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:

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:
