[Fix] Add the panel to DPCD quirk table to use DPCD to control the panel backlight. [Test] 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.
