[PATCH 04/46] drm/i915: Move connector registration to driver registration
Chris Wilson

Thu Jun 23 10:52:46 UTC 2016
Defer connector registration from during construction to the driver
registration phase. This is important for ordering the action correctly,
e.g. not using debugfs before it is ready.
