[PATCH virtio v3 02/13] virtio_pci: simplify vp_request_msix_vectors() call a bit

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jiri Pirko <jiri@xxxxxxxxxx>

Pass desc arg as it is always to vp_request_msix_vectors(). There rely
on per_vq_vectors arg and null desc in case it is false.
