Subject: ACPI / video: Add force_native quirk for Dell XPS 17 L702X

From: Hans de Goede <[email protected]>

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.
