Possibly but devres should have released all resources after the
previous probe failure or driver disassociation, so I have no idea how
there can be resources left on that list.

devres hasn't changed, so I have no idea what changed that.  Which
kernels are affected?  Can you bisect if the problem is easily
reproducible?

Thanks.
