OK, that makes sense, even if it is unfortunate. I'm fairly certain that my
HDMI and DP connectors are connected to the dGPU, even if I never use them. So
it makes sense that a backlight device get's created for that, I guess. Too bad
that the code commentary says that there is no way to check whether it is
actually needed, apparently.
