After the "ACPI: video: Make backlight class device registration a separate step" patch from earlier in this patch-series, we no longer briefly register the acpi_video0 backlight on systems where the native driver should be used. So this is no longer an issue an the quirk is no longer needed. Acked-by: Rafael J.
