> Cannot change brightness on HP ZBook Fury with certain panel.
> Add the panel to DPCD quirk table to use DPCD to control the panel
> Changing backlight sysfs doesn't change the display brightness.
> With the patch applied, changing sysfs backlight can really change the
> display brightness.
> [Where problems could occur]
> This fix is specific to a single panel, so it's not likely to cause any
> regression to other devices.
