-Use DRM_MODESET_LOCK_ALL_* helpers instead of boilerplate
----------------------------------------------------------
-
-For cases where drivers are attempting to grab the modeset locks with a local
-acquire context. Replace the boilerplate code surrounding
-drm_modeset_lock_all_ctx() with DRM_MODESET_LOCK_ALL_BEGIN() and
-DRM_MODESET_LOCK_ALL_END() instead.
-
-This should also be done for all places where drm_modeset_lock_all() is still
-used.
-
-As a reference, take a look at the conversions already completed in drm core.

 acquire context. Furthermore the acquire context keeps track of debugging state
