Ah, so lkp bisected it to that commit, which means it was
already broken in 6.5, but I'm fairly sure the bug is even
older then, as your commit seems to have only uncovered
an existing problem.

It was definitely working before ff3cc65cadb5 ("media: v4l: async,
fwnode: Improve module organisation") in linux-5.13, but it's not
clear if that is the culprit. It's probably safe to backport
to v5.15 and higher.
