From 5d13349472ac8abcbcb94407969aa0fdc2e1f1be Mon Sep 17 00:00:00 2001 From: Geliang Tang geliang@kernel.org Date: Fri, 15 Aug 2025 19:28:22 +0200 Subject: [PATCH] mptcp: remove duplicate sk_reset_timer call
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.
