I'd rather see this as
if (virZPCIDeviceAddressIsEmpty(&dev->addr.pci.zpci))
return 0;
return qemuAppendZPCIDevStr(cmd, dev);
instead.
How about using switch? I think extension flag should be check and
then build command for each case although there's only zpci case.
You can't really sensibly use a switch() for flags. Unless I have
mistaken what you had in mind...
Like below simple code,
if (dev->type != PCI_TYPE || dev->addr.pci.extFlags == NONE)
return 0;
if (dev->addr.pci.extFlags & ZPCI_FLAG)
return qemuAppendZPCIDevStr(cmd, dev);
/* There might be new extensions in future. */
return 0;
