Subject: [PATCH v2] drm/virtio: Remove redundant return type
Date: Mon,  6 May 2019 11:10:34 +0200	[thread overview]
Message-ID: <20190506091034.30289-1-robert.foss@collabora.com> (raw)

virtio_gpu_fence_emit() always returns 0, since it
has no error paths.

Consequently no calls for virtio_gpu_fence_emit()
use the return value, and it can be removed.
