Subject: [PATCH v2 22/25] arm/stm32f205 arm/stm32f405: Fix realize error API violation
Date: Wed, 24 Jun 2020 10:37:34 +0200	[thread overview]
Message-ID: <20200624083737.3086768-23-armbru@redhat.com> (raw)
In-Reply-To: <20200624083737.3086768-1-armbru@redhat.com>

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.

stm32f205_soc_realize() and stm32f405_soc_realize() are wrong that
way: they pass &err to object_property_set_int() without checking it,
and then to qdev_realize().  Harmless, because the former can't
actually fail here.

Fix by passing &error_abort instead.
