Subject: [PATCH 3/8] drm/virtio: use virtio_gpu_object->hw_res_handle in virtio_gpu_resource_create_ioctl()
Date: Mon,  1 Oct 2018 12:32:17 +0200	[thread overview]
Message-ID: <20181001103222.11924-4-kraxel@redhat.com> (raw)
In-Reply-To: <20181001103222.11924-1-kraxel@redhat.com>

Drop pointless res_id variable in virtio_gpu_resource_create_ioctl(),
just use the hw_res_handle field in virtio_gpu_object directly.
