Subject: [PATCH] backlight: lp855x: Make sure props struct is zeroed
Date: Thu, 27 Aug 2015 17:41:15 +0000	[thread overview]
Message-ID: <1440697275-4469-1-git-send-email-bjorn.andersson@sonymobile.com> (raw)

From: Werner Johansson <werner.johansson@sonymobile.com>

The driver occasionally got stuck in suspend mode or other strange
states as those parts of the props struct were never initialized.
