Even if the parent can't be locked, you should still try to lock the
device.

I have considered doing it, but which may consume another 1sec.

Also if the parent lock has been held, it is very possibly that the
device can't be probed or removed at the same time, so just logged
the crazy thing and go ahead.

Okay.  Then you can add my Acked-by.
