X-Git-Tag: v3.6-rc4~11^2~10^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8ab08c0c4c39f36d3bf89e03a4bc3e6898e1563c;p=profile%2Fivi%2Fkernel-x86-ivi.git

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]
