[Qemu-devel] [PULL v2 02/11] acpi-build: properly decrement objects' reference counters

["Michael S. Tsirkin" <mst@redhat.com>]

From: Kirill Batuzov <batuzovk@ispras.ru>

Object returned by object_property_get_qobject needs its reference counter to
be decremented when it is not needed by caller anymore.
