Subject: drm/i915: Make DP-MST connector info work
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.
Fixes: 9a148a96fc3a ("drm/i915/debugfs: add dp mst info")
