> From: Andre Eikmeyer <dev@deq.rocks>

> When GMUX routes the internal panel to the integrated GPU, the eDP link
> of the AMD GPU has no sink. It still exposed panel_power_savings, and
> tuned writes it on every switch between AC and battery. Each write sends
> a hotplug event and the following connector probe runtime resumes the
> GPU that GMUX had powered off. Only create the attribute when the link
> has a panel.
