this callback was used by drm_kms_helper_hotplug_event()
V2: (Thanks for Daniel's suggestions) - remove the FIXME below.since with the drm_client - infrastructure and the generic fbdev emulation we've - resolved this all very neatly now.
V3: Add comments that This hook is deprecated - new implementation methods instead of this hook
