You are changing here order of calls: psr_reg after bind, it does not
seem to be related to patch subject.
Anyway psr_register can fail and its result is not checked, but it can
be addressed in separate patch.
So maybe it would be better to leave the order as is, unless there is
reason for change it in one patch, in such case please explain it in
commit message.
Beside this:
