Merge tag 'drm-fixes-2018-09-12' of git://anongit.freedesktop.org/drm/drm

Pull drm nouveau fixes from Dave Airlie:
 "I'm sending this separately as it's a bit larger than I generally like
  for one driver, but it does contain a bunch of make my nvidia laptop
  not die (runpm) and a bunch to make my docking station and monitor
  display stuff (mst) fixes.

  Lyude has spent a lot of time on these, and we are putting the fixes
  into distro kernels as well asap, as it helps a bunch of standard
  Lenovo laptops, so I'm fairly happy things are better than they were
  before these patches, but I decided to split them out just for
  clarification"
