Date: Wed, 5 Mar 2014 14:22:48 +0000 From: Luis Henriques <luis.henriques@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Ilia Mirkin <imirkin@...m.mit.edu>, Ben Skeggs <bskeggs@...hat.com>, Luis Henriques <luis.henriques@...onical.com> Subject: [PATCH 3.11 044/131] drm/nouveau: set irq_enabled manually 3.11.10.6 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Ilia Mirkin <imirkin@...m.mit.edu> commit 7d3428cd4b2ad51af86fdbdf8284ca38fa95e601 upstream. Since commit 0fa9061ae8c ("drm/nouveau/mc: handle irq-related setup ourselves"), drm_device->irq_enabled remained unset. This is needed in order to properly wait for a vblank event in the generic drm code.
