When the 'parent' was added to the virNodeDevicePtr structure by commit id 'e8a4ea75a' the 'parent' field was not properly filled in when a virGetNodeDevice call was made within driver/config code. Only the device name was ever filled in. Fetching the parent required a second trip via virNodeDeviceGetParent into the node device lookup code was required in order to retrieve the specific parent field (and still the parent field was never filled in although it was free'd). Since we have the data when we initially call virGetNodeDevice from within driver/node_config code - let's just fill in the parent field as well for anyone that wants it without requiring another trip into the node_device lookup just to get the parent. This will allow API's such as virConnectListAllNodeDevices, virNodeDeviceLookupByName, and virNodeDeviceLookupSCSIHostByWWN to retrieve both name and parent in the returned virNodeDevicePtr.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
