remoteproc: rename len of rpoc_vring to num
Rename the member len in the structure rpoc_vring to num. And remove 'in bytes' from the comment of it. This is misleading. Because this actually refers to the size of the virtio vring to be created. The unit is not bytes. Signed-off-by: Xuan Zhuo <xuanzhuo@linux.alibaba.com> Message-Id: <20220624025621.128843-2-xuanzhuo@linux.alibaba.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
