Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost

Pull virtio/vdpa fixes from Michael Tsirkin:
 "Fixes up some issues in rc1"

* tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost:
  vdpa: potential uninitialized return in vhost_vdpa_va_map()
  vdpa/mlx5: Avoid executing set_vq_ready() if device is reset
  vdpa/mlx5: Clear ready indication for control VQ
  vduse: Cleanup the old kernel states after reset failure
  vduse: missing error code in vduse_init()
  virtio: don't fail on !of_device_is_compatible
