This causes acpi_video_use_native_backlight() to always think that a value was specified through the param, making it impossible to add a dmi based quirk to force 0 now that the default is 1. This fixes this by restoring the use_native_backlight_param default to -1, and instead setting the use_native_backlight_dmi default to true.
