+Subject: [PATCH 5253/5725] drm/amd/display: Fix memory leak caused by missed
+ dc_sink_release
+
+[Why]
+There is currently an intermittent hang from a memory leak in
+DTN stress testing. It is caused by unfreed memory during driver
+disable.
+
+[How]
+Do a dc_sink_release in the case that skips it incorrectly.
