powerpc/xmon: Fix -Wswitch-unreachable warning in bpt_cmds
[ Upstream commit1c4a4a4c84
] 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:09b6c1129f
