Subject: drm/udl: Drop drm_vblank_cleanup
Git-commit: 5cbdaccb0df9a57936ba3608e97433fc469954cb
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

udl doesn't shut down the display, so stopping the vblank isn't going
to do much good either. Just drop it.
