ACPI: video: Add backlight=native DMI quirk for Lenovo ThinkPad X131e (3371 AMD version)
Linux defaults to picking the non-working ACPI video backlight interface on the Lenovo ThinkPad X131e (3371 AMD version). Add a DMI quirk to pick the working native radeon_bl0 interface instead. Signed-off-by: Hans de Goede <[email protected]> Signed-off-by: Rafael J. Wysocki <[email protected]>
