From 178b6e8da07eb0f32658dee463f615b787522328 Mon Sep 17 00:00:00 2001 From: Victor Erminpour Date: Wed, 9 Feb 2022 16:28:38 -0800 Subject: [PATCH] net: mpls: Fix GCC 12 warning When building with automatic stack variable initialization, GCC 12 complains about variables defined outside of switch case statements. Move the variable outside the switch, which silences the warning: ./net/mpls/af_mpls.c:1624:21: error: statement will never be executed [-Werror=switch-unreachable] 1624 | int err; | ^~~ Signed-off-by: Victor Erminpour Signed-off-by: David S.
