[media] v4l2-tpg: ignore V4L2_DV_RGB_RANGE setting for YUV formats
The V4L2_DV_RGB_RANGE_* settings are, as the name says, for RGB formats only. So they should be ignored for non-RGB formats. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
