Subject: [PATCH] virtio-gpu: no point of checking res->iov
Date: Mon, 30 Aug 2021 10:50:33 -0700	[thread overview]
Message-ID: <20210830175033.29233-1-dongwon.kim@intel.com> (raw)

The code should check the opposite condition of res->iov because it will be null
if virtio_gpu_create_mapping_iov fails and actually this checking is not even
required because checking on ret covers all failing cases.
