Keyboard backlight turns on by itself

Bug Description

On my Thinkpad T440s

1. Make sure keyboard backlight is off
2. Wait for the screen to blank due to inactivity
3. Wake the screen and unlock the machine*

Expected behavior: The keyboard backlight is in its original (off) state
Actual behavior: FULL BRIGHTNESS!

* As I haven't been paying close enough attention, I'm not sure at exactly which step in this process the light turns on, but I have correlated it to resuming from screen blanking.

@Brian, this seems to be the same, but that bug is for Xenial and a fix is already released. I'll test out the patch in lp:1510344 to see if its a regression or not when I have a chance.

@Brian the unity-settings-daemon in the aforementioned branch doesn't resolve the issue. This seems like a new bug affecting Yakkety.

FTR we also get reports of this happening on trusty with Lenovo X1 Carbon hardware, so it's not just xenial and yakkety
