dmesg with override bit patch

I've added a dmesg dump of kernel 4.7.2 with two of your patches (backported):

  drm/i915: Debug GBDA get panel details
  drm/i915: Ignore OpRegion panel type unless the "override" bit is set 

The result is that my screen doesn't switch on anymore. I've tested with
vanilla 4.7.2 as well, and that works OK.

Is the output OK for you? If you want me to test further patches, no problem.
