Just various stuff all over from a bunch of people. Shortlog gives a beter
overview, it's really all misc drm patches.

* tag 'topic/core-stuff-2014-11-05' of git://anongit.freedesktop.org/drm-intel:
  drm/edid: add #defines and helpers for ELD
  drm/dp: Add counters in the drm_dp_aux struct for I2C NACKs and DEFERs
  drm: Remove compiler BUG_ON() test
  drm: Fix DRM_FORCE_ON_DIGITAL use
  drm/gma500: Don't destroy DRM properties in the driver
  drm/i915: Don't destroy DRM properties in the driver
  drm: Add a note to drm_property_create() about property lifetime
  gpu: drm: Fix warning caused by a parameter description in drm_crtc.c
  drm/dp-helper: Move the legacy helpers to gma500
  drm/crtc: Remove duplicated ioctl code
  drm/crtc: Fix two typos
  gpu:drm: Fix typo in Documentation/DocBook/drm.xml
  gpu: drm: drm_dp_mst_topology.c: Fix improper use of strncat
  drm: drm_err: Remove unnecessary __func__ argument
  drm: Implement O_NONBLOCK support on /dev/dri/cardN
