Subject: [PATCH net-next 9/9] mptcp: pass addr to mptcp_pm_alloc_anno_list

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

Pass addr parameter to mptcp_pm_alloc_anno_list() instead of entry. We
can reduce the scope, e.g. in mptcp_pm_alloc_anno_list(), we only access
"entry->addr", we can then restrict to the pointer to "addr" then.
