 - minor kAPI update for the request API

 - some fixes at CEC core

 - use a lower minimum height for the virtual codec driver

 - cleanup a gcc warning due to the lack of a fall though markup

 - tc358743: Remove unnecessary self assignment

 - fix the V4L event subscription logic

 - docs: Document metadata format in struct v4l2_format

 - omap3isp and ipu3-cio2: fix unbinding logic
