Subject: qemu: Resolve Coverity IDENTICAL_BRANCHES
X-Git-Tag: v1.2.16-rc1~125
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9ad32e5052ecce9ae6a328201c624fe45b7b2dc4;p=thirdparty%2Flibvirt.git

qemu: Resolve Coverity IDENTICAL_BRANCHES

Coverity complains that in the error paths both the < 0 condition and
the success path after the qemuDomainObjExitMonitor failure will end
up going to cleanup.  So just use ignore_value in this error path to
resolve the complaint.
