Subject: [PATCH 18/22] virtio_rpmsg_bus: use simplified virtqueue accessors.
Date: Mon, 18 Mar 2013 20:04:49 +1030	[thread overview]
Message-ID: <1363599293-23065-19-git-send-email-rusty@rustcorp.com.au> (raw)
In-Reply-To: <1363599293-23065-1-git-send-email-rusty@rustcorp.com.au>

We never add buffers with input and output parts, so use the new accessors.
