[PATCH 0/4 v2] drm: introduce drm_connector_register_all() helper

[Alexey Brodkin]

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 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()

Alexey Brodkin (4):
  drm: rename drm_connector_unplug_all() to
    drm_connector_unregister_all()
  drm: introduce drm_connector_register_all() helper
  drm: atmel_hldc - use generic drm_connector_register_all() helper
  drm: rcar-du - use generic drm_connector_register_all() helper
