Message

Here is the first part of my virtio-sound patches. Most of them are a
preparation to make migration work. Patch 09/10 enables migration of the
virtio-sound device.

The second part isn't finished yet and will have to do with virtio-sound
jack and channel maps configuration and migration.

Volker Rümelin (10):
  hw/audio/virtio-sound: remove command and stream mutexes
  hw/audio/virtio-sound: allocate all streams in advance
  hw/audio/virtio-sound: split out virtio_snd_pcm_start_stop()

  hw/audio/virtio-sound: introduce virtio_snd_set_active()
