If anyone has any objections, please let me know. ------------------ From: Hans de Goede commit 350fa038c31b056fc509624efb66348ac2c1e3d0 upstream. The Dell XPS 17 L702X has a non-working acpi_video0 backlight interface and an intel_backlight interface which works fine. Add a force_native quirk for it so that the non-working acpi_video0 interface does not get registered. Note that there also is an issue with the brightnesskeys on this laptop, they do not generate key-press events in anyway. That is not solved by this patch.
