Subject: [v3 09/10] drm: mediatek: Omit warning on probe defers

From: Matthias Brugger <>

When probe through the MFD, 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.
