void ctcm_ccw_check_rc	(	struct channel *	ch,
		int	rc,
		char *	msg
	)

Check return code of a preceding ccw_device call, halt_IO etc...

ch : The channel, the error belongs to. Returns the error code (!= 0) to inspect.

void ctcm_chx_txidle	(	fsm_instance *	fi,
		int	event,
		void *	arg
	)

Initial data is sent. Notify device statemachine that we are up and running.

fi An instance of a channel statemachine. event The event, just happened. arg Generic pointer, casted from channel * upon call.
