ACPI: PM: Loop in full LPS0 mode only
After a previous change, all non-wakeup GPEs are disabled for suspend-to-idle unless full Low-Power S0 (LPS0) mode is in use, so it is not necessary to do anything in acpi_s2idle_wake() unless in full LPS0 mode, which is only when lps0_device_handle is set. Modify the code accordingly. Tested-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
