Subject: drm/nouveau: set irq_enabled manually
From: Ilia Mirkin <imirkin@xxxxxxxxxxxx>
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.
See https://bugs.freedesktop.org/show_bug.cgi?id=74195
