Subject: util: make read error of PCI config file more detailed
X-Git-Tag: v7.0.0-rc1~217
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0003f5808ff12ca529ed52016dbf346195880c78;p=thirdparty%2Flibvirt.git

util: make read error of PCI config file more detailed

The new message is more verbose/useful, but only logged at debug level
instead of as a warning (since it could easily happen in a non-error
situation).
