Oliver Hartkopp c142cba37d can: af_can: fix NULL pointer dereference in can_rcv_filter ... commit 0acc442309 upstream. Analogue to commit 8aa59e3559 ("can: af_can: fix NULL pointer dereference in can_rx_register()") we need to check for a missing initialization of ml_priv in the receive path of CAN frames. Since commit 4e096a1886 ("net: introduce CAN specific pointer in the struct net_device") the check for dev->type to be ARPHRD_CAN is not sufficient anymore since bonding or tun netdevices claim to be CAN devices but do not initialize ml_priv accordingly.
