From: Grazvydas Ignotas <notasas@xxxxxxxxx>
Subject: backlight-add-support-for-pandora-backlight-v2
changed in v2: fixed a bug where setting brightness to 0 twice
would actually turn the backlight on.
We had this driver in pandora tree for a couple of years now, but
while cleaning it up for mainline submission I've introduced this
bug, sorry for the noise.
