4d471563d8 media: i2c: Fix pm_runtime_get_if_in_use() usage in sensor drivers
pm_runtime_get_if_in_use() returns -EINVAL if runtime PM is disabled. This
should not be considered an error. Generally the driver has enabled
runtime PM already so getting this error due to runtime PM being disabled
will not happen.

Instead of checking for lesser or equal to zero, check for zero only.
Address this for drivers where this pattern exists.

This patch has been produced using the following command:

$ git grep -l pm_runtime_get_if_in_use -- drivers/media/i2c/ | \
  xargs perl -i -pe 's/(pm_runtime_get_if_in_use\(.*\)) \<\= 0/!$1/'

d508fffb92 media: ov5670, ov13858: Use pm_runtime_idle
Replace the calls to pm_runtime_get_noresume() and pm_runtime_put() with
pm_runtime_idle() in the driver's probe function. This will have the same
effect with fewer calls. pm_runtime_disable() in remove is sufficient as
the device is already in RPM_SUSPENDED state.

d2dc57b10a media: v4l: Bring back array_size parameter to v4l2_find_nearest_size
An older version of the driver patches were merged accidentally which
resulted in missing the array_size parameter that tells the length of the
array that contains the different supported sizes.

Bring it back to v4l2_find_nearest size and make the corresponding change
for the drivers using it as well.

d365bc9247 media: ov13858: Avoid possible null first frame
Previously, the sensor, with default settings, was outputting SOF without
data. This results in frame sync error on the receiver side.

Now, configure the sensor to output SOF with MIPI data for all frames. This
avoids possible null first frame on the bus.

58020c9f14 [media] media: ov13858: Fix 4224x3136 video flickering at some vblanks
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.

Previously, vblank range given to user was too big, falling outside
of permissible range for a given resolution. Sometimes, too low vblank
resulted in errors.

Now, limit vblank to only permissible range for a given resolution.
This change limits lower-bounds of vblank, doesn't affect upper bounds.

bfced6d1ec media: ov13858: Increase digital gain granularity, range
Previously, possible digital gains were just 1x, 2x and 4x. These
coarse gains were not sufficient in fine-tuning the image capture.

Now, digital gain range is [0, 16x] with each step 1/1024, default 1x.
This is achieved through OV13858 MWB R/G/B gain controls.

b3775edc66 media: ov13858: Set default fps as current fps
On format change, sometimes, sensor was streaming at a much higher
FPS than the default. This was resulting in various problems like
frame drops/corruption.

Upon format change, set default vblank as current vblank. This will
ensure that sensor will start streaming at default fps.
