From c6a7b026a3a80662d8f7bb6b4f7821329aa7111b Mon Sep 17 00:00:00 2001 From: Lauri Peltonen Date: Thu, 26 Feb 2015 13:16:48 +0900 Subject: [PATCH] drm/nouveau/gr/gf100: Clear notify interrupt Notify interrupt is only used for cyclestats. We can just clear it and avoid an "unknown stat" error that gets printed to dmesg otherwise.
