Subject: [PATCH v1 0/2] Virtio: fix some vq allocation issues

Some vqs don't need to be allocated when the related feature bits are
disabled. Callers notice the vq allocation layer by setting the related
names[i] to be NULL.

This patch series fixes the find_vqs implementations to handle this case.

Wei Wang (2):
  virtio_pci: use queue idx instead of array idx to set up the vq
  virtio: don't allocate vqs when names[i] = NULL
