From: Kuniyuki Iwashima Commit 383eed2de529 ("tcp: get rid of twsk_unique()") added sk->sk_protocol test in __inet_check_established() and __inet6_check_established() to remove twsk_unique() and call tcp_twsk_unique() directly. DCCP has gone, and the condition is always true. Let's remove the sk_protocol test.
