[PATCH 1/2] mfd: ab8500-gpadc: add CONFIG_PM_RUNTIME toruntime_suspend/runtime_resume

From: Jingoo Han
Date: Fri Aug 02 2013 - 01:21:00 EST

Add CONFIG_PM_RUNTIME to runtime_suspend/runtime_resume functions
to fix the build warnings when CONFIG_PM_RUNTIME is not selected.
This is because runtime PM callbacks defined by SET_RUNTIME_PM_OPS
are only used when the CONFIG_PM_RUNTIME is enabled.
