Tetsuo Handa 1809c82aa0 net: can: j1939: j1939_xtp_rx_rts_session_active(): deactivate session upon receiving the second rts ... Since j1939_session_deactivate_activate_next() in j1939_tp_rxtimer() is called only when the timer is enabled, we need to call j1939_session_deactivate_activate_next() if we cancelled the timer. Otherwise, refcount for j1939_session leaks, which will later appear as | unregister_netdevice: waiting for vcan0 to become free. Usage count = 2. problem.
