From 6fa1b5b1364195cc5a42f7e629a1d1863cfff69f Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Wed, 29 Jan 2014 19:53:00 -0500 Subject: drm/nouveau: set irq_enabled manually 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.
