Output of "brightnessctl -l" for Lenovo 16ARH7

It seems the brightness keys (Fn+F5,Fn+F6) do not work in the latest Tumbleweed
KDE snapshot on the Lenovo Slim 7 16" AMD, 16ARH7, 82UX0001US (and this same
model is called Yoga outside the United States). It seems the internal
display's brightness values are bugged and show up as 0 and "0 (-2147483648%)"
in brightnessctl rather than something within the expected range.

I've attached the output of "brightnessctl -l", which shows the display and
some of the keyboard/charging LEDs on the laptop.

Glad to provide any other logs that could be helpful. Hope this is the right
place to report this.

Thanks!
