Oliver Hartkopp af94ef8f0b can: gw: synchronize rcu operations before removing gw job entry ... commit fb8696ab14adadb2e3f6c17c18ed26b3ecd96691 upstream. can_can_gw_rcv() is called under RCU protection, so after calling can_rx_unregister(), we have to call synchronize_rcu in order to wait for any RCU read-side critical sections to finish before removing the kmem_cache entry with the referenced gw job entry.
