Merge branch 'drm-next-3.13' of git://people.freedesktop.org/~agd5f/linux into drm-next 

One last patch I keep forgetting to include.  Fix for EDID quirk
handling.  Been on the list and reviewed for several months now,
I just keep forgetting about it.

* 'drm-next-3.13' of git://people.freedesktop.org/~agd5f/linux:
  drm/edid: compare actual vrefresh for all modes for quirks
hifive-unleashed-5.1
