The function, vhost_vdpa_alloc_domain(), has a pointer to a struct bus_type, but it should be constant as the function it passes it to expects it to be const, and the vhost code does not modify it in any way.

The dev_attrs field of struct bus_type is going away soon, dev_groups should be used instead. This converts the virtio bus code to use the correct field.
