Subject: qom: strdup() target property name on object_property_add_alias()
X-Git-Tag: v2.4.0-rc0~42^2~13
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1590d266d96b3f9b42443d6388dfc38f527ac2d8;p=thirdparty%2Fqemu.git

qom: strdup() target property name on object_property_add_alias()

With this, object_property_add_alias() callers can safely free the
target property name, like what already happens with the 'name' argument
to all object_property_add*() functions.
