Subject: [PATCH net-next 4/4] mptcp: drop unused sk in mptcp_push_release

From: Geliang Tang <geliang.tang@...e.com>

Since mptcp_set_timeout() had removed from mptcp_push_release() in
commit 33d41c9cd74c5 ("mptcp: more accurate timeout"), the argument
sk in mptcp_push_release() became useless. Let's drop it.

Fixes: 33d41c9cd74c5 ("mptcp: more accurate timeout")
