From: zhangzhijie <zhangzhijie@xxxxxxxxxxx>
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
