The original intent of the virtio header relicensing from 2008 was to make sure anyone can implement compatible devices/drivers. The virtio-ccw was omitted by mistake. We have an ack from the only contributor as well as the maintainer from IBM, so it's not too late to fix that. Make it dual-licensed with GPLv2, as the whole kernel is GPL2.
