From 7a309cc95b862be74711e7a35997daa3f885651a Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 14 Jul 2020 18:02:00 +0200 Subject: qom: Change object_get_canonical_path_component() not to malloc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit object_get_canonical_path_component() returns a malloced copy of a property name on success, null on failure. 19 of its 25 callers immediately free the returned copy. Change object_get_canonical_path_component() to return the property name directly. Since modifying the name would be wrong, adjust the return type to const char *. Drop the free from the 19 callers become simpler, add the g_strdup() to the other six.
