+Subject: [PATCH 2/2] Revert "drm/vc4: hdmi: Make sure the device is powered with CEC" again
+
+This reverts commit 9b0d360fd783c711fc1cafa51f3e03bdf8ca5518 which is
+commit 20b0dfa86bef0e80b41b0e5ac38b92f23b6f27f9 upstream.
+
+It wasn't applied correctly, something went wrong with an attempt to fix
+it up again, so just revert the whole thing to be back at a clean state.
