Suspicious indeed.

But probably it's better to move the unref below instead of removing the
ref/unref (see below).

A device is ref'ed when install/uninstall starts and is unref'ed when
install/uninstall finishes.

Possibly during install the ref is not needed (as there is another ref
for the redir operation),
but I think it is needed during uninstall.

It wasn't needed until now (or we would have had crashes before), why would it be now?

Generally, no crashes does not mean ref/unref are not needed.
