The issue ended up being much more complicated however, as we also apparently needed to add support for an Intel-specific DPCD backlight control interface as the VESA interface is broken on many laptop panels. For lack of a better name, we just call this the Intel HDR backlight interface. While this only adds support for the SDR backlight mode (I think), this will fix a lot of user's laptop panels that we weren't able to properly automatically detect DPCD backlight controls on previously.
