[Qemu-devel] [PATCH v8 03/19] hw/vfio/pci: generalize mask/unmask to any IRQ index

[Eric Auger <eric.auger@linaro.org>]

To prepare for platform device introduction, rename vfio_mask_intx
and vfio_unmask_intx into vfio_mask_single_irqindex and respectively
unmask_single_irqindex. Also use a nex index parameter.

With that name and prototype the function will be usable for other
indexes than VFIO_PCI_INTX_IRQ_INDEX.
