Subject: [PATCH] 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.
