+Subject: [PATCH] overlays: fsm-demo: Ensure all LEDs are turned off
+
+If the shutdown process is delayed enough to trigger the shutdown
+timeout then one or more states in the shutdown sequence might be
+skipped. Ensure that all LEDs are turned off regardless by explicitly
+doing so in the shutdown state, as an example of good practices.
