Subject: drm/atmel: Drop drm_vblank_cleanup
Git-commit: e3ec0e1e38a57ced1449b09be23e87da5d91e2b8
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Again almost correct, but since interrupts are shut down after vblank
still a race. Proper cleanup would call drm_atomic_helper_shutdown to
make sure this really is safe.

v2: Remove misplace malidp hunk (Liviu).
