From b09aea7fb38f328c02e9f9b79617cabed02455e4 Mon Sep 17 00:00:00 2001 From: Zhenyu Wang Date: Sat, 19 Sep 2009 14:54:06 +0800 Subject: [PATCH] drm/i915: Fix typo for wrong LVDS clock setting on IGDNG New register for PCH LVDS on IGDNG should be used. This is a copy-n-paste typo. This fixes possible dual channel LVDS panel failure on IGDNG.
