can: Do not call dev_put if restart timer is running upon close
commit ab48b03ec9ae1840a1e427e2375bd0d9d554b4ed upstream. If the restart timer is running due to BUS-OFF and the device is disconnected an dev_put will decrease the usage counter to -1 thus blocking the interface removal, resulting in the following dmesg lines repeating every 10s: can: notifier: receive list not found for dev can0 can: notifier: receive list not found for dev can0 can: notifier: receive list not found for dev can0 unregister_netdevice: waiting for can0 to become free. Usage count = -1 Signed-off-by: Alexander Stein <alexander.stein@systec-electronic.com> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
