[PULL 37/53] include/hw/virtio: make some VirtIODevice const

Posted by Michael S. Tsirkin 2 years, 7 months ago

From: Hawkins Jiawei <yin31149@gmail.com>

The VirtIODevice structure is not modified in
virtio_vdev_has_feature(). Therefore, make it const
to allow this function to accept const variables.
