      Here are some drm core fixes for v4.4 that I've picked up. Atomic fixes
      from Maarten, and atomic helper fixes from Ville and Daniel.
      
      Admittedly the topmost commit didn't sit in our tree for very long, but
      does come with reviews and testing from trustworthy people.

      This was totally lost when I originally created the atomic helpers.
      
      We probably should also check possible_clones in the helpers, but
      since the legacy ones didn't do that this is for a separate patch.

      commit 6764e9f8
      Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
      Date:   Thu Aug 27 15:44:06 2015 +0200
      
          drm/i915: skip modeset if compatible for everyone.
      
      Bring back the i915.fastboot module parameter, disabled by default, due
      to backlight regression on Chromebook Pixel 2015.
      
      Apparently the firmware of the Chromebook in question enables the panel
      but disables backlight to avoid a brief garbage scanout upon loading the
      kernel/module. With fastboot, we leave the backlight untouched, in this
      case disabled. The user would have to do a modeset (i.e. not just crank
      up the brightness) to enable the backlight.
      
      There is no clean fix readily available, so get back to the drawing
      board by reverting.

      The cursor code may be entered with file_priv == NULL && handle == NULL.
      The problem was introduced by:
      
      "bf89209a drm/mga200g: Hold a proper reference for cursor_set"
      
      which calls drm_gem_object_lookup(dev, file_priv...). Previously this wasn't
      a problem because we checked the handle. Move the check early in the function
      can fix the problem.
