[PATCH 0/6] virtio-console: spec compliance fixes

[Michael S. Tsirkin]

Turns out virtio console tries to take a buffer out of an active vq.
Works by sheer luck, and is explicitly forbidden by spec.  And while
going over it I saw that error handling is also broken -
failure is easy to trigger if I force allocations to fail.

Lightly tested.

Michael S. Tsirkin (6):
  virtio_console: don't tie bufs to a vq
  virtio: add ability to iterate over vqs
  virtio_console: free buffers after reset
  virtio_console: drop custom control queue cleanup
  virtio_console: move removal code
  virtio_console: reset on out of memory
