Subject: util: storage: Report errors when source host data is missing
X-Git-Tag: v3.5.0-rc1~55
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=299aff7e0cd52c50da518eeed676144d373e9281;p=thirdparty%2Flibvirt.git

util: storage: Report errors when source host data is missing

Merge the reporting of the missing source host data into the parser
functions so that callers don't have to do it separately.
