From d662986b4f282ed5d9e42e6dbd5e6dbb2b5e7d0b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 29 Aug 2013 12:21:01 +0100 Subject: [PATCH] clk: wm831x: Initialise wm831x pointer on init commit 08442ce993deeb15a070c14cc3f3459e87d111e0 upstream. Otherwise any attempt to interact with the hardware will crash. This is what happens when drivers get written blind.
