[PATCH 0/4 v3] drm: Introduce drm_connector_register_all() helper

From: Alexey Brodkin
Date: Wed Mar 23 2016 - 04:43:16 EST

As a pair to already existing drm_connector_unplug_all()
(which we'll rename in this series to drm_connector_unregister_all())
we're adding generic implementation of what is already done in some drivers
for registering all connectors.

After implementation of that new helper we're updating 2 drivers
that used to use it's own implementation:
[1] atmel_hlcdc
[2] rcar_du

And one driver that uses unregister():
[1] udl

Other drivers still use load() callback and so should be first modified so
their load() gets called from their probe() explicitly.

Build- and run-tested on yet to be upstreamed ARC PGU (part of AXS10x board).

Changes v2 -> v3:
* Added acks for 1, 3 and 4 patches
* Updated kerneldoc descriptins of both register_ and unregister_all()
* Updated commit messages (mostly spellos and grammar issues)

Changes v1 -> v2:
* Rename drm_connector_unplug_all() to drm_connector_unregister_all()
* Use drm_for_each_connector() instead of list_for_each_entry()
* Updated kerneldoc for drm_dev_register()
