To me it seems better to keep this as is, to be
used by .probe and .release methods, in the same way
usb_get_dev() and usb_put_dev() are used by usb drivers.
Hiding refcounts under the resource accessors will just
complicate things unnecessarily. Modifying refcounts
should always be explicit unless there's a very good
reason against it.
