From 1c4a4a4c8410be4a231a58b23e7a30923ff954ac Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Fri, 16 Sep 2022 15:15:04 +0100 Subject: [PATCH] powerpc/xmon: Fix -Wswitch-unreachable warning in bpt_cmds MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When building with automatic stack variable initialization, GCC 12 complains about variables defined outside of switch case statements. Move the variable into the case that uses it, which silences the warning: arch/powerpc/xmon/xmon.c: In function ‘bpt_cmds’: arch/powerpc/xmon/xmon.c:1529:13: warning: statement will never be executed [-Wswitch-unreachable] 1529 | int mode; | ^~~~ Fixes: 09b6c1129f89 ("powerpc/xmon: Fix compile error with PPC_8xx=y") Signed-off-by: Gustavo A.
