[PATCH 1/4 v2] drm: rename drm_connector_unplug_all() to drm_connector_unregister_all()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Current name is a bit misleading because what that helper function
really does it calls drm_connector_unregister() for all connectors.

This all has nothing to do with hotplugging so let's name things
properly.

And while at it remove potentially dangerous locking around
drm_connector_unregister() in rcar_du_remove() as mentioned
in kerneldoc for drm_connector_unregister_all().
