Is a linked device supposed to be unregistered automatically before
the parent? The referenced document mentions only suspending
and resuming, nothing about unregistering.
I tried
device_link_add(parent, &ptp->dev, DL_FLAG_AUTOREMOVE_CONSUMER);
and also with no flags specified, but it didn't seem to do anything
for the vclock. It was still oopsing.
Any hints?
