If anyone has any objections, please let me know. ------------------ From: Jean-Philippe Brucker [ Upstream commit 92aef4675d5b1b55404e1532379e343bed0e5cf2 ] Currently when virtio_find_single_vq fails, we go through del_vqs which throws a warning (Trying to free already-free IRQ). Skip del_vqs if vq allocation failed.
