Oh, it's me who suggests there was an issue in nouveau since I don't know
nouveau has a logic to check if ACPI video will support backlight control on
this system and then do things accordingly.
#ifdef CONFIG_ACPI
if (acpi_video_backlight_support()) {
NV_INFO(drm, "ACPI backlight interface available, "
"not registering our own\n");
return 0;
}
#endif
I'm not sure if this is correct, I think nouveau can always create backlight
interface for user to use no matter if other module do that or not. Just my
personal opinion.
