From 80a92865f2113fe8bc268218b0c4156cfab4c9ac Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Tue, 28 Mar 2017 11:46:37 +1000 Subject: [PATCH] drm/nouveau/fb/ram/gf100-: remove 0x10f200 read This reg has moved on Pascal, and causes a bus fault. We never use the value anyway, so just remove the read.
