Colin Ian King 62c04647c6 can: bcm: check for null sk before deferencing it via the call to sock_net ... The assignment of net via call sock_net will dereference sk. This is performed before a sanity null check on sk, so there could be a potential null dereference on the sock_net call if sk is null. Fix this by assigning net after the sk null check. Also replace the sk == NULL with the more usual !sk idiom.
