Description:
Changing the brightness using function key is buggy. The key is working but the problem is when the value changes. Using 'cat /sys/class/backlight/intel_backlight/brightness' I got the brightness values as such:

244
488
976
488
976
4882 (max)
4394
244

As you can see the values are not changed equally (like increase 10% each time).

Additional info:
* package version(s)
* config and/or log files etc.

Arch kernel version: 4.8.6-1-ARCH
The error log is attached, please let me know if more information is required.

Steps to reproduce:
This bug started occurring after full system upgrade. 'pacman -Syu'
