** Description changed: [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://patchwork.freedesktop.org/patch/394304/ [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.
