powerpc/process: Fix uninitialised variable error
Clang, and GCC with -Wmaybe-uninitialized, can't see that val is unused in get_fpexec_mode(): arch/powerpc/kernel/process.c:1940:7: error: variable 'val' is used uninitialized whenever 'if' condition is true if (cpu_has_feature(CPU_FTR_SPE)) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ We know that CPU_FTR_SPE will only be true iff CONFIG_SPE is also true, but the compiler doesn't. Avoid it by initialising val to zero. Reported-by:kernel test robot <lkp@intel.com> Fixes: 532ed190 ("powerpc/process: Remove useless #ifdef CONFIG_SPE") Signed-off-by:
