ACPI: Print message before calling _PTS
Make acpi_sleep_prepare() static and cause it to print a message specifying the ACPI system sleep state to be entered (helpful for debugging the suspend/hibernation code). Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Pavel Machek <pavel@suse.cz> Signed-off-by: Len Brown <len.brown@intel.com>
