Backlight hotkeys weren't working before on certain cedartrail laptops. The source of this problem is that the hotkeys' ASLE opregion interrupts were simply ignored. Driver seemed to expect the interrupt to be associated with a pipe, but it wasn't. Accepting the ASLE interrupt without an associated pipe event flag fixes the issue, the backlight code is called when needed, making the brightness keys work properly.
