Commit Message

Hans de Goede Aug. 25, 2022, 2:37 p.m. UTC 
Remove the asus-wmi quirk_entry.wmi_backlight_native quirk-flag, which
called acpi_video_set_dmi_backlight_type(acpi_backlight_native) and replace
it with acpi/video_detect.c video_detect_dmi_table[] entries using the
video_detect_force_native callback.

acpi_video_set_dmi_backlight_type() is troublesome because it may end up
getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers
already being registered even though they should not.
