Wysocki 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 when lps0_device_handle is set only. Modify the code accordingly. Signed-off-by: Rafael J.
