[PATCH v2 00/17] rcar-vin: fix issues with format and capturing

["Niklas Söderlund" <niklas.soderlund@ragnatech.se>]

From: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>

Hi,

This series fix a number of issues for the rcar-vin driver regarding
format and capturing. It is based on top of '[GIT PULL FOR v4.13] V4L2 
fwnode support' and tested on Koelsch.

Parts of this series where previously part of '[PATCH 00/11] media:
rcar-vin: fix OPS and format/pad index issues'. But after good reviews
a large part of that series where dropped.

* Changes since v1
- Do not consider the lack of a subdevice sink pad an error instead
  default to use pad 0 in such case. This keeps the behavior of the
  driver which previous versions of this series changed.
- When printing pad numbers print using %u not %d as they are unsigned.
- Keep comment in code which was lost when moving code around.
- If trying to set an unsupported pixel format do not switch the current
  format, instead switch to the first supported format of the driver to
  achieve a more deterministic behaviour.
- Add new patch to remove redundant checks in the async bind/unbind
  callbacks.
- Clarify some commit messages, thanks Laurent!
- Fix typos in commit messages, thanks Sergei and Laurent!
- Add Reviewed-by tags from Lauren
