6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geliang Tang tanggeliang@kylinos.cn
commit 5d13349472ac8abcbcb94407969aa0fdc2e1f1be upstream.
sk_reset_timer() was called twice in mptcp_pm_alloc_anno_list.
Simplify the code by using a 'goto' statement to eliminate the duplication.
Note that this is not a fix, but it will help backporting the following patch. The same "Fixes" tag has been added for this reason.
