No, you are mistaken.  In the original patch, NULL or PTR_ERR were
returned on error, and that was not a bug.

If you want to correct the present version of ptp_clock_register() to
always return a valid pointer or PTR_ERR (like the kerneldoc says), be
my guest, but please say that in the change log and reference the
correct commit (namely the one related to disabling POSIX clocks.)

Thanks,
Richard
