Missing curly braces.
Also, do you really need to check both the flags and the presence
of the zPCI address bits? It looks like either one or the other
should be enough or, if that's not the case, it should be made so
because having to check for two separate conditions makes me feel
like it would introduce bugs in the long run.
This is actually a problem. I add info->addr.pci.zpci check in order to
check
if the user specifies zpci address in xml even though it has no zpci
support.
The callers of this function checks zpci capability. If no zpci cap but
the user
specfies zpci address, report an error.
I will change the logic and remove the check on info->addr.pci.zpci.

Is this really necessary? Can't these two functions be static?
They are also used in qemu_hotplug.c file.
