[libvirt] [PATCH 01/15] util: Introduce VIR_DEFINE_AUTOPTR_FUNC for virStorageAuthDef
John Ferlan

Wed Feb 6 13:41:33 UTC 2019
Let's make use of the auto __cleanup capabilities cleaning up any
now unnecessary goto paths. For virStorageAuthDefCopy use authdef
and ret as consistently as similar other code.
