From e59a8db8d9b7c02e0bbefbeb18a3836288a97b8a Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sat, 14 Jan 2012 00:39:36 +0100 Subject: PM / Domains: Skip governor functions for CONFIG_PM_RUNTIME unset The governor functions in drivers/base/power/domain_governor.c are only used if CONFIG_PM_RUNTIME is set and they refer to data structures that are only present in that case. For this reason, they shouldn't be compiled at all when CONFIG_PM_RUNTIME is not set. Reported-by: Kukjin Kim Signed-off-by: Rafael J.
