From 602c43d34dcd46b0349b31c9b53b19cd5063ae3f Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Wed, 8 Aug 2012 14:15:30 -0300 Subject: [PATCH] drm/i915: completely reset the value of DDI_FUNC_CTL Don't rely on previous values already set on the register. Everything we're not explicitly setting should be zero for now.
