Remove the asus-wmi quirk_entry.wmi_backlight_power quirk-flag, which called acpi_video_set_dmi_backlight_type(acpi_backlight_vendor) and replace it with acpi/video_detect.c video_detect_dmi_table[] entries using the video_detect_force_vendor 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. Note no entries are dropped from the dmi_system_id table in asus-nb-wmi.c. This is because the entries using the removed wmi_backlight_power flag also use other model specific quirks from the asus-wmi quirk_entry struct. So the quirk_asus_x55u struct and the entries pointing to it cannot be dropped. Acked-by: Rafael J.
