| 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. |
