ARM: shmobile: r8a7779: hide unused r8a7779_platform_cpu_kill
After the cleanup in r8a7779_smp_prepare_cpus(), the only remaining caller of r8a7779_platform_cpu_kill() is in an ifdef, which leads to a build warning without CONFIG_HOTPLUG_CPU: arch/arm/mach-shmobile/smp-r8a7779.c:26:12: error: 'r8a7779_platform_cpu_kill' defined but not used [-Werror=unused-function] This moves the function inside of that #ifdef to avoid the warning. Fixes: 62f55ce683e3 ("ARM: shmobile: r8a7779: Stop powering down secondary CPUs during early boot") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
