Dan Carpenter dbdfefc71a virtio_ring: Fix two use after free bugs ... [ Upstream commit e152d8af4220a05c9797591609151d404866beaa ] The "vq" struct is added to the "vdev->vqs" list prematurely. If we encounter an error later in the function then the "vq" is freed, but since it is still on the list that could lead to a use after free bug.
