Oleksij Rempel 143df6b358 can: j1939: socket: j1939_sk_bind(): make sure ml_priv is allocated ... commit af804b7826 upstream. This patch adds check to ensure that the struct net_device::ml_priv is allocated, as it is used later by the j1939 stack. The allocation is done by all mainline CAN network drivers, but when using bond or team devices this is not the case. Bail out if no ml_priv is allocated.
