Hi developers!
In my ThinkPad X230 and ThinkPad T430 regulate backlight works
incorrectly.
I test with xrandr all value, but some value not working. I attach
LogFile with test results.
This problem present since kernel 3.5 or 3.6.
Before max_backlight = 15. After = 100.
In other devices (IdeaPad Z580, Acer 5220, etc.) works correct.
What component has bug ?

Igor Gnatenko
