+Subject: [PATCH] vchiq_arm: Service callbacks must not fail
+
+Service callbacks are not allowed to return an error. The internal callback
+that delivers events and messages to user tasks does not enqueue them if
+the service is closing, but this is not an error and should not be
+reported as such.
