[PATCH] v4l2: Ensure interlace-mode is mixed whenever hardware does interlaced


There exists component video capture hardware capable of supporting both
720x576i25 and 720x576p25 formats. Test interlaced mode before progressive,
so that our caps are interlace-mode=mixed whenever buffers can be
interlaced.
