csiostor driver is triggering WARN_ON with this patch
drivers/pci/msi.c:1193
1172 int pci_alloc_irq_vectors_affinity(struct pci_dev *dev, unsigned int min_vecs,
1173 unsigned int max_vecs, unsigned int flags,
1174 const struct irq_affinity *affd)
1175 {
1176 static const struct irq_affinity msi_default_affd;
1177 int vecs = -ENOSPC;
1178
1179 if (flags & PCI_IRQ_AFFINITY) {
...
1192 } else {
1193 if (WARN_ON(affd))
1194 affd = NULL;
1195 }
PCI_IRQ_AFFINITY flag is missing
+ cnt = pci_alloc_irq_vectors_affinity(hw->pdev, min, cnt, PCI_IRQ_MSIX,
+ &desc);
+ if (cnt < 0)
return cnt;
