Thinkpad t14s brightness stuck at 100%

Just got my thinkpad t14s (amd) today! and downloaded Ubuntu surprisingly everything works amazing besides the brightness being stuck at 100% which isn't to terrible to battery but still drains a bit. I gotta say the ryzen 4000 series on linux is next level battery life in general is amazing.

Fixed: Upgrade kernel to 5.8 or higher, i used mainline kernel manager
