Which stops acpi_video from registering a backlight interface, but this is only a partial fix, because for people who have the ideapad-laptop module installed that module will now register a backlight interface, which also does not work, so we need to use the native intel_backlight interface. The Lenovo Ideapad 570 is a pre-win8 laptop / too old for the acpi-video code to automatically prefer the native backlight interface, so add a quirk for it. This commit also removes the previous incomplete fix. Link: https://bugzilla.redhat.com/show_bug.cgi?id=1187004 Tested-by: Be Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
