patch: always update the props.brightness
two problems about the backlight sysfs I/F.
1. the "brightness" doesn't reflect the actual brightness value.
2. setting the "brightness" file doesn't change the backlight.
For the first problem, I'd say that it's the
"/sys/class/backlight/.../actual_brightness" that reports the current backlight
levels.
The "brightness" file just returns a cached value.
For the second problem, could you please try this patch and see if it helps?
Note that please DO NOT touch the "actual_brightness" file during the test.
