| Subject: [PATCH 13/14] acpi-video: Add use native backlight quirk for the
 | |
|  ThinkPad W530
 | |
| 
 | |
| Like all of the other *30 ThinkPad models, the W530 has a broken acpi-video
 | |
| backlight control. Note in order for this to actually fix things on the
 | |
| ThinkPad W530 the commit titled:
 | |
| "nouveau: Don't check acpi_video_backlight_support() before registering backlight"
 | |
| is also needed.
