The R-Car DU driver calls drm_vblank_init via some helper functions in probe(). From what I checked, most drivers do this as well. I have a config now where DU always stays in deferred_probe state because of a missing dependency. This means that every time I rebind another driver like MMC, the vblank init message is displayed again when the DU driver is retried. Because the message doesn't really carry a useful information, I suggest to simply drop it.

Makes sense, queued up in drm-misc-next. -Daniel
