Re: Check connect address in NETLINK

Why don't you combine the two "ERR_PTR(-ECONNREFUSED)" tests
into one test like:

        if ((nlk->pid == 0 && !nlk->data_ready) ||
            (sock->sk_state == NELTINK_CONNECTED &&
             nlk->dst_pid != nlk_sk(ssk)->pid)) {
                sock_put(sock);
                return ERR_PTR(-ECONNREFUSED);
        }

so we don't have two copies of the "sock_put(); return ERR_PTR()"
thing emitted by the compiler?
