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. -- You are receiving this mail because: You are the assignee for the bug.
