I'd suggest moving this cleanup to a separate commit so that you keep
the fix itself as small as possible and thus minimize the potential of
introducing regressions in stable kernels that will receive the fix.

Also, per convention please use the if-clause to catch the error case,
not the success case.  It doesn't matter if you need two or three more
lines, readability is more important IMO.

Thanks,
