Re: platform/x86: asus-wmi: Keyboard backlight brightness does not work correctly on Asus ROG Zephyrus G15

Nevermind, upon further digging I found https://lore.kernel.org/all/20240713074733.77334-2-luke@ljones.dev/, which wasn't pulled into
my downstream kernel yet and verified that it does work for me.

Thanks,
