Subject: drm/atomic: Call ww_acquire_done after drm_modeset_lock_all
Git-commit: 5fcdc9d9816266c575ef21586327ba04d7db5c2c
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
After we acquired all generic modeset locks in drm_modeset_lock_all, it's
unsafe acquire any other so just mark acquisition as done.
Atomic drivers shouldn't use drm_modeset_lock_all.
