[PATCH 4/8] scripts: qemu-replies-tool: List also data from 'qom-list-properties'

29 Aug 2025

From: Peter Krempa <pkrempa@redhat.com>

In addition to 'device-list-properties' libvirt probes also some
properties of qom types. Since the format is identical make the dumping
function for 'device-list-properties' universal and make it accept also
'qom-list-types'.
