[PATCH] virNodeDevPCICapSRIOVVirtualParseXML: fix memleak of addr

Posted by Hao Wang 3 years, 9 months ago

From: Hao Wang <wanghao232@huawei.com>
Subject: [PATCH] virNodeDevPCICapSRIOVVirtualParseXML: fix memleak of addr

virPCIDeviceAddressPtr 'addr' is forgotten to be freed in the branch
'VIR_APPEND_ELEMENT() < 0'. Use g_autoptr instead.
