This is a follow-up series from Vandana's "[v3] v4l2-core: Add metadata type to
vfl_devnode_type" patch: https://patchwork.linuxtv.org/patch/58755/
While testing that v3 patch with a patched version of vivid that has metadata
capture support, I realized that metadata should be treated the same way as
vbi in determine_valid_ioctls(). That makes sense since vbi *is* effectively
metadata. So I changed Vandana's patch (hence my Co-Developed-by tag) to
correctly validate the ioctls for metadata.
I also added two follow-up patches to simplify the SDR code in that function,
and to fix the code for v4l-touch devices (too many ioctls were enabled for
such devices). I think the final code is easier to read as well.
Regards,
Hans
