Bug Description
[Impact]
Current driver fails to parse VBT 234+ and gets wrong brightness levels.
It leads to screen dim completely when brightness is set to lowest.
[Fix]
We need the commits to parse VBT 234+
https:/
[Test]
Verified on Dell machines
[Where problems could occur]
The patches are simple and with a separate flow control for VBT 234,
should have no impact for current brightness control.
