From 9f9317159fdafe3d7fc64cf41f299c71c064db83 Mon Sep 17 00:00:00 2001 From: Florian Tobias Schandinat Date: Wed, 22 Feb 2012 18:53:08 +0000 Subject: [PATCH 44/95] viafb: fix IGA1 modesetting on VX900 commit e29206381a1436e0f47c0f5b9a23159a03c57715 upstream. Even if the documentation calls this bit "Reserved" it has to be set to 0 for correct modesetting on IGA1.
