Hi,


I have found the sysfs attribute for brightness control to be in 
/sys/class/backlight/asus_screenpad, and it appears on both 6.12.90 and 
6.12.94.

On 6.12.90, max_brightness reports 235.

On 6.12.94, max_brightness reports 255.


I have checked out to v6.12.94, reverted the suspect commit, and found 
the ScreenPad to be working as intended.


Regards,

Ponali
