Add the missed function call to fix it.
...

ring->irq = pci_irq_vector(ring->nhi->pdev, ring->vector);
- if (ring->irq < 0)
+ if (ring->irq < 0) {
+ ida_simple_remove(&nhi->msix_ida, ret);
return ring->irq;
+ }
irqflags = no_suspend ? IRQF_NO_SUSPEND : 0;
return request_irq(ring->irq, ring_msix, irqflags, "thunderbolt", ring);
According to your logic don't you need it here as well?
Hm indeed. Will fix too.

Thanks for your review.
