Commit Message

Laurent Pinchart Feb. 15, 2021, 4:26 a.m. UTC 
The imx_media_video_dev structure stores the active format on the video
node in an instance of v4l2_format. This wastes memory when all we need
is the information contained in the smaller v4l2_pix_format
sub-structure. Replace v4l2_format by v4l2_pix_format to save memory.
