There are no technical difficulties with that, but it would be
inconsitent wrt other "device table"-aware buses (i2c, pci, of).

Note that I'm getting rid of probe_id function in patch 5/7, as a
cleanup step. I want to keep "new features" and "api cleanups"
separate. That way it's easier to review the changes.

Thanks!
