Merge tag 'vfio-v6.15-rc3' of https://github.com/awilliam/linux-vfio

Pull vfio fix from Alex Williamson:

 - Include devices where the platform indicates PCI INTx is not routed
   by setting pdev->irq to zero in the expanded virtualization of the
   PCI pin register. This provides consistency in the INFO and SET_IRQS
   ioctls (Alex Williamson)
