Subject: [PATCH net-next 4/4] mptcp: drop lookup_by_id in lookup_addr
From: Geliang Tang <tanggeliang@...inos.cn>
When the lookup_by_id parameter of __lookup_addr() is true, it's the same
as __lookup_addr_by_id(), it can be replaced by __lookup_addr_by_id()
directly. So drop this parameter, let __lookup_addr() only looks up address
on the local address list by comparing addresses in it, not address ids.
