From 897a6e27fd44573d2f346d9bb122e0e29759952c Mon Sep 17 00:00:00 2001 From: Marcin Slusarz Date: Sat, 2 Mar 2013 20:00:31 +0100 Subject: [PATCH] drm/nouveau/drm: fix crash in vram manager debug callback It's probably impossible to hit it now on mainline kernel. I only noticed it because one of my debugging patches uses it.
