ARM: exynos: exynos_pm_add_dev_to_genpd may be unused
exynos_pm_add_dev_to_genpd is used if one or more out of a large number of Kconfig symbols are enabled. However the new exynos_defconfig selects none of those, so the function becomes unused. Marking it so lets the compiler automatically discard it. Without this patch, building exynos_defconfig results in: arch/arm/mach-exynos/pm_domains.c:118:123: warning: 'exynos_pm_add_dev_to_genpd' defined but not used [-Wunused-function] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Thomas Abraham <thomas.abraham@linaro.org> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Cc: Rafael J.
