--- Comment #6 from Sandor Ecker (esanya at freemail.hu) ---
So it seems that the 16 bit actual_brightness is not a bug, but a feature... :)

https://github.com/torvalds/linux/commit/262485a50fd4532a8d71165190adc7a0a19bcc9e#diff-b496037255b7766a782d3f3711b50db8

So my question now:
-why are the max_brightness and brightness values in 8bit range?
