Can the patch be safely applied without the above driver present? FWIW, this patch does not seem to apply cleanly on renesas-next-20170110-v4.10-rc2.

It will result in DU probing being deferred forever, so I'd say no :-) > FWIW, this patch does not seem to apply cleanly on > renesas-next-20170110-v4.10-rc2. I'll fix the conflicts and resubmit when the driver lands.
