[PULL 26/28] hw/arm/armsse: Fix armsse_realize() error API violation

From: Markus Armbruster
Subject: [PULL 26/28] hw/arm/armsse: Fix armsse_realize() error API violation
Date: Thu, 2 Jul 2020 13:09:29 +0200

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

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

Fix by passing &error_abort instead.
