From 9069240480e24a2d6ce23404c9ad6cabf59b7258 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 9 Aug 2012 23:00:02 +0200 Subject: ACPI / PM: Fix unused function warnings for CONFIG_PM_SLEEP According to compiler warnings, several suspend/resume functions in ACPI drivers are not used for CONFIG_PM_SLEEP unset, so add #ifdefs to prevent them from being built in that case.
