Subject[PATCH 4.12 171/196] drm/i915: Make DP-MST connector info work
Date
4.12-stable review patch.  If anyone has any objections, please let me know.

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

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

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.

Fixes: 9a148a96fc3a ("drm/i915/debugfs: add dp mst info")
