Agree that the code is incorrect. Just wanted to understand if you had any functionality impact too.

I tried to reproduce the problem in PC environment but did not see the warnings.
However, I tried your patch and did plug/unplug tests(rmmod/insmod continuously) and observed call traces from kernel. I don't see these traces without your patch.
Attached log.
