Subject: [PATCH] acpi: video: Add a quirk to force acpi-video backlight on Dell XPS L421X
Date: Mon, 26 Oct 2015 15:20:46 +0100 [thread overview]
Message-ID: <1445869246-29276-1-git-send-email-hdegoede@redhat.com> (raw)
Just like the Dell XPS 15 (L521X) the Dell XPS 14 (L421X) needs to use
the acpi-video backlight interface rather then the native one for backlight
control to work, add a quirk for this.
