Subject: [PATCH 213/232] 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.
