If the fix wasn't fixing a problem, it wouldn't be a fix :-) The reason
why I don't think this is worth a backport is that it only fixes an
issue reported by v4l2-compliance, that hasn't to my knowledge affected
anyone in other use cases. Given that the driver evolves, backporting
this change blindly, testing compilation only but not runtime operation,
has a higher risk of introducing failures in stable kernels than it has
a chance to fix issues that affect people.
