Please note that for some unknown reason neither v6 nor v7 ever reached the
linux-media mailinglist. Can you try to repost, this time just to the mailinglist
and with a CC to me?
I have seen this problem before but it was never clear why linux-media would
reject it. If you have an alternative email address you can email from, then
you can try that as well.

You must compile v4l2-compliance from the v4l-utils git repo. You can tell because
the SHA will be shown. That way I can be certain you tested with the latest
v4l2-compliance.

5.10 is really quite old, is it possible to test with a newer kernel?
