Subject: Check for NULL in qemu monitor event filter
X-Git-Tag: v1.2.9-rc2~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b987c4c3f4829eb8a0134b687cb9748ff724f98a;p=thirdparty%2Flibvirt.git

Check for NULL in qemu monitor event filter

When virConnectDomainQemuMonitorEventRegister is called with the
VIR_CONNECT_DOMAIN_QEMU_MONITOR_EVENT_REGISTER_REGEX flag,
ignore the flag instead of crashing.
