Subject: [PATCH net-next 02/13] mptcp: drop argument port from mptcp_pm_announce_addr

From: Geliang Tang <geliangtang@...il.com>

Drop the redundant argument 'port' from mptcp_pm_announce_addr, use the
port field of another argument 'addr' instead.

Fixes: 0f5c9e3f079f ("mptcp: add port parameter for mptcp_pm_announce_addr")
