Subject: ACPI / video: Add force_native quirk for HP Pavilion dv6
From: Hans de Goede <hdegoede@redhat.com>
commit 6276e53fa8c06a3a5cf7b95b77b079966de9ad66 upstream.
The HP Pavilion dv6 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 are quite a few HP Pavilion dv6 variants, some
woth ATI and some with NVIDIA hybrid gfx, both seem to need this
quirk to have working backlight control. There are also some versions
with only Intel integrated gfx, these may not need this quirk, but it
should not hurt there.
