The recent changes to perform SCSI device address checks during the post parse callbacks ran afoul of the Coverity checker since the changes assumed that the 'xmlopt' parameter to virDomainDeviceDefPostParse would be non NULL (commit id 'ca2cf74e87'); however, what was missed is there was an "if (xmlopt &&" check being made, so Coverity believed that it could be possible for a NULL 'xmlopt'. Checking the various calling paths seemingly disproves that. If called from virDomainDeviceDefParse, there were two other possible calls that would end up dereffing, so that path could not be NULL. If called via virDomainDefPostParseDeviceIterator via virDomainDefPostParse there are two callers (virDomainDefParseXML and qemuParseCommandLine) which deref xmlopt either directly or through another call. So I'm removing the check for non-NULL xmlopt.
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.
