+Switch to drm_connector_list_iter for any connector_list walking
+----------------------------------------------------------------
+
+Connectors can be hotplugged, and we now have a special list of helpers to walk
+the connector_list in a race-free fashion, without incuring deadlocks on mutexes
+and other fun stuff.

+Unfortunately most drivers are not converted yet. At least all those supporting
+DP MST hotplug should be converted, since for those drivers the difference
+matters. See drm_for_each_connector_iter() vs. drm_for_each_connector().
