( https://gerrit.osmocom.org/10637 Change subject: cosmetic: lchan_fsm failure: log about state transitions ...................................................................... cosmetic: lchan_fsm failure: log about state transitions Early on during failure, log which state transition is intended after failure handling. If such state is already reached after failure handling, do not log "state transition not permitted", but rather skip the state change and log "Already in state X".
