[PATCH 4.12 171/196] drm/i915: Make DP-MST connector info work

From: Greg Kroah-Hartman
Date: Tue Jul 25 2017 - 15:34:47 EST


4.12-stable review patch. If anyone has any objections, please let me know.

------------------

From: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxxxx>

commit 50740024bc393b608f7e391ac35e70f33938dd24 upstream.

Commit 9a148a96fc3a ("drm/i915/debugfs: add dp mst info") adds support
for DP-MST to intel_connector_info, but forgot to remove the early
return for DP-MST.

Remove it, and print out MST connectors directly.
