The default value is _MODEL_NAME_NONE aka zero, which is still part
of the enumeration, so virDomainControllerPCIModelNameTypeToString()
won't return NULL and no error will be raised. For pSeries guests,
it will be set to _MODEL_NAME_SPAPR_PCI_HOST_BRIDGE so once again no
problem there.

His efforts on switch normalization and me rebasing this series
happened pretty much at the same time; more specifically, the
function you're talking about was introduced in 3b1020ac805e, while
my series is based on the earlier f565321b26df.
I guess this means another rebase! Yay! \o/
