From: Matthias Brugger <mbrugger@suse.com> It can happen that the clock drivers wasn't probed before the ddp driver gets invoked. The driver used to omit a warning that the driver failed to get the clocks. Omit this error on the defered probe path.
so if we list drm device as a child device of mmsys we don't need the patch, and that make more sense.
