Hello, On my Zephyrus G15 (GA503RM-G15.R93060), my keyboard brightness controls do not work. I believe I have traced this down to being a kernel issue, based on the fact that my Gnome control center slider and `asusctl -k` do result in `/sys/class/leds/asus::kbd_backlight/brightness` being updated, but the changed value of `/sys/class/leds/asus::kbd_backlight/brightness` is not reflective of the actual brightness of my keyboard, which always remains unchanged. (I can also confirm that other keyboard/fan control features do work, such as the keyboard profile switcher, custom fan curves, etc. - so it just seems to be the brightness that is broken.) If this is likely just a case where I would need to poke around my hardware to find the correct values to write for brightness control to work on my specific SKU, I would be happy to do that and contribute it back here, but I will need some guidance on where to look for that info. Let me know if that would be helpful, or if there's any other info I can provide to help fix this bug. Thanks, Mitchell Augustin
