Hi, This series aims to reduce the amount of boiler plate code in video device drivers who's inputs and/or outputs are controlled by the Media Controller instead of the V4L2 API. Patch 1/3 adds a new video device capability flag V4L2_CAP_IO_MC which if set provides helper implementations for the enum inputs and outputs ioctrls freeing the video device driver from the need to implement them. Patch 2/3 and 3/3 converts the R-Car VIN and Intel IPU3 drivers to use the new default handlers and capability flag and delete the now redundant boiler plate code. I'm sure more video device drivers can make use of this new flag but as I can only test on these two platforms I have limited my changes to those.
