Merge tag 'topic/drm-misc-2015-04-15' of git://anongit.freedesktop.org/drm-intel into drm-next

One more drm-misch pull for 4.1 with mostly simple stuff and boring
refactoring. Even the cursor fix from Matt is just to make a really anal
igt happy.

* tag 'topic/drm-misc-2015-04-15' of git://anongit.freedesktop.org/drm-intel:
  drm: fix trivial typo mistake
  drm: Make integer overflow checking cover universal cursor updates (v2)
  drm: make crtc/encoder/connector/plane helper_private a const pointer
  drm/armada: constify struct drm_encoder_helper_funcs pointer
  drm/radeon: constify more struct drm_*_helper funcs pointers
  drm/edid: add #defines for ELD versions
  drm/atomic: Add for_each_{connector,crtc,plane}_in_state helper macros
  drm: Use kref_put_mutex in drm_gem_object_unreference_unlocked
  drm/drm: constify all struct drm_*_helper funcs pointers
  drm/qxl: constify all struct drm_*_helper funcs pointers
  drm/nouveau: constify all struct drm_*_helper funcs pointers
  drm/radeon: constify all struct drm_*_helper funcs pointers
  drm/gma500: constify all struct drm_*_helper funcs pointers
  drm/mgag200: constify all struct drm_*_helper funcs pointers
  drm/exynos: constify all struct drm_*_helper funcs pointers
  drm: Fix some typos
