This text is inadequate.  It does not identify the problem.  What
resources?  Which related device?

> Fix this by calling pps_unregister_source() in ptp_clock_release().

This statement is redundant, as we can see that from the patch itself.
Instead of saying WHAT the patch does, please explain WHY that fixes
the issue (which, as I said, you still need to identify).

Thanks,
