Subject: [PATCH] backlight: Fix dimmed display doesn't go to sleep

Firmware didn't start sleep countdown if
1. Display was already dimmed
2. Fade out timer was set

You can reproduce this by:
1. Set fade out timer. For example, 500ms
2. Wait till display will be dimmed and go to sleep
3. Switch hold ON or plug headphones
