Linux kernel 6.12 fails to load asus-nb-wmi

[JustScreaMy]

Describe the bug

After updating to the kernel 6.12, my ASUS Zenbook UX3402ZA keyboard backlight stopped working, after looking through the logs and differenes between 6.11 and 6.12, I have found out that kernel module asus-nb-wml fails to load with error -5.

I'm not sure which other issues this will show, but the Backlight is the most obvious I have noticed so far

Steps To Reproduce

Steps to reproduce the behavior:

1. Upgrade kernel from 6.11 to 6.12
2. Try to increase or decrease keyboard backlight
3. There isnt an option and the shortcut isnt working

Expected behavior

Keyboard backlight will work normally
