From: Geliang Tang <geliang.tang@xxxxxxxx>
commit 528cb5f2a1e859522f36f091f29f5c81ec6d4a4c upstream.
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.
