I put those into a new immutable branch (based on 5.12-rc2), topic/virtio, and tagged it as virtio_snd-5.12-rc2. Michael, if you need to pull the stuff into your tree for further changes, feel free to take from git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git tags/virtio_snd-5.12-rc2 Thanks!
