[PATCH 12/12] conf: Convert virDomainHostdevDefParseXMLSubsys() to virXMLProp*()
Michal Privoznik

Fri Jan 21 13:28:19 UTC 2022
After previous cleanups, the virDomainHostdevDefParseXMLSubsys()
function uses a mixture of virXMLProp*() and the old
virXMLPropString() + virXXXTypeFromString() patterns. Rework it
so that virXMLProp*() is used.
