Subject: qemuMonitorJSONHandleTrayChange: Properly handle if 'devAlias' is missing
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=8eb09a2bb984f3550cc87074e57841b86be39601;p=libvirt.git

qemuMonitorJSONHandleTrayChange: Properly handle if 'devAlias' is missing

While qemu is still reporting the 'device' field in the tray even the
code was not ready for the possibility of it missing. Fix the condition
for clearing 'devAlias' if qemu doesn't report the 'device' field.
