ACPI suspend: Fix compilation warnings in drivers/acpi/sleep.c
Fix two compilation warnings in drivers/acpi/sleep.c, one triggered by unsetting CONFIG_SUSPEND and the other triggered by unsetting CONFIG_HIBERNATION, by moving some code under the appropriate #ifdefs . Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Len Brown <len.brown@intel.com>
