[Intel-gfx] [PATCH v2 23/29] platform/x86: asus-wmi: Move acpi_backlight=native quirks to ACPI video_detect.c

Hans de Goede
2022-07-12T19:41:29Z

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.
