Adding support for controlling panel backlights over the DP AUX channel on certain laptops featuring hybrid Intel/Nvidia GPU setups, so that the backlight may be controlled while the laptop is in discrete mode. Previously, laptops with backlights using DP AUX for backlight control could only control their backlights while operating in Hybrid mode.
