(Sorry for the noise, had to resend because I typo'd amd's mailing list
email address by accident)

Just resubmitting this patch series from AMD with _very_ minor changes
(just a typo and fixing a debug message) so that this can be pushed
upstream with a proper patchwork link. Will be pushing this into a topic
branch and submitting to airlied in a moment.

  drm: Remove slot checks in dp mst topology during commit
  drm: Update MST First Link Slot Information Based on Encoding Format
  drm/amd/display: Add DP 2.0 MST DM Support
