Once the DIR* in virPCIGetName() was made g_autoptr, the cleanup:
label just had a "return ret;", but the rest of the function was more
compilcated than it needed to be, doing funky things with the value of
ret inside multi-level conditionals and a while loop that might exit
early via a break with ret == 0 or exit early via a goto cleanup with
ret == -1.
It really didn't need to be nearly as complicated. After doing the
trivial replacements of "goto cleanup" with appropriate direct
returns, it became obvious that:
1) the outermost level of the nested conditional at the end of the
function ("if (ret < 0)") was now redundant, since ret is now
*always* < 0 by that point (otherwise the function has returned).
2) by switching the sense of the next level of the conditional (making
it "if (!physPortID)", the "else" (which is now just "return 0;"
becomes the "if", and the new "else" no longer needs to be inside
the conditional.
3) the value of firstEntryName can be moved into *netname with
g_steal_pointer()
Once that is all done, ret is no longer used and can be removed.

Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
