Series [v2] vimc: cap: Report a colorspace | expand

Commit Message

Niklas Söderlund April 17, 2020, 3:09 p.m. UTC 
The colorspace reported by a video nodes should not be
V4L2_COLORSPACE_DEFAULT. Instead a default colorspace should be picked
by the driver if V4L2_COLORSPACE_DEFAULT is given by userspace to
{G,S,TRY}_FMT.

The colorspace V4L2_COLORSPACE_SRGB is arbitrary chosen as the vimc
default format to report as it's used for most webcams.
