Now applied all patches to sound.git tree for-next branch.

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!
