Subject: [PATCH] backlight: lp855x: set zero brightness at FBBLANK
Date: Tue, 02 Jul 2013 12:15:54 +0000 [thread overview]
Message-ID: <1372767354-16499-1-git-send-email-oskar.andero@sonymobile.com> (raw)
From: Shingo Nakao <shingo.x.nakao@sonymobile.com>
When backlight turns on early from display, a white line can be
seen on the screen. Therefore make sure backlight is off when we
are under an fb blank event.
