Subject: virtio_ring: switch to use vring_virtqueue for enable_cb_prepare variants
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=74847cb5731760b22ace8e2fe97a330aa0162d1e;p=thirdparty%2Flinux.git

virtio_ring: switch to use vring_virtqueue for enable_cb_prepare variants

Those variants are used internally so let's switch to use
vring_virtqueue as parameter to be consistent with other internal
virtqueue helpers.
