+Subject: [PATCH 7/8] Revert "drm/amd/display: Fix memory leaks in S3 resume"
+
+This reverts commit a135a1b4c4db1f3b8cbed9676a40ede39feb3362.
+
+This leads to blank screens on some boards after replugging a
+display.  Revert until we understand the root cause and can
+fix both the leak and the blank screen after replug.
