From 17d5d49a4e877b08ebf82aa33b349176281e68a3 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 30 Jun 2020 11:03:49 +0200 Subject: [PATCH] hw/arm/armsse: Fix armsse_realize() error API violation MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. armsse_realize() is wrong that way: it passes &err to object_property_set_int() multiple times without checking it, and then to sysbus_realize(). Harmless, because the former can't actually fail here. Fix by passing &error_abort instead.
