Subject: media: v4l2-ioctl.c: use check_fmt for enum/g/s/try_fmt
From: Hans Verkuil <[email protected]>
commit b2469c814fbc8f1f19676dd4912717b798df511e upstream.
Don't duplicate the buffer type checks in enum/g/s/try_fmt. The check_fmt function does that already.
It is hard to keep the checks in sync for all these functions and in fact the check for VBI was wrong in the _fmt functions as it allowed SDR types as well. This caused a v4l2-compliance failure for /dev/swradio0 using vivid.
This simplifies the code and keeps the check in one place and fixes the SDR/VBI bug.
