From: Hans de Goede Date: Tue, 29 Nov 2016 14:32:15 +0000 (+0100) Subject: ACPI / video: Add force_native quirk for Dell XPS 17 L702X X-Git-Tag: firefly_0821_release~176^2~4^2~6^2~47 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2c2375e40d28b3d0fd961448fd12963f66b4b452;p=firefly-linux-kernel-4.4.55.git ACPI / video: Add force_native quirk for Dell XPS 17 L702X 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.
