Prior to this update, using the libvirt-tck utility to find the parent device of a node device with no parent incorrectly returned a "libvirt error code: 0" error message. Now, it is valid for the virNodeDeviceGetParent() function to return NULL if the parent device is nonexistent, and the error message is no longer displayed.
