This suggests that you are running with an old(er) v4l-utils version, since I adapted
v4l2-compliance to avoid this failure. It's due to a change in the kernel, so currently
both old and new descriptions are accepted.

Looking at the logs:

v4l2-compliance SHA: 5d8c459c1bf9 2021-04-08 13:28:26

That's much too old.
