Subject: [RFC PATCH 02/13] vsock: remove vm_sockets_get_local_cid()
Date:   Fri, 27 Sep 2019 13:26:52 +0200
Message-Id: <20190927112703.17745-3-sgarzare@redhat.com>
In-Reply-To: <20190927112703.17745-1-sgarzare@redhat.com>

vm_sockets_get_local_cid() is only used in virtio_transport_common.c.
We can replace it calling the virtio_transport_get_ops() and
using the get_local_cid() callback registered by the transport.
