Subject: [PATCH v3 25/26] arm/{bcm2835, fsl-imx25, fsl-imx6}: Fix realize error API violations
Date: Tue, 30 Jun 2020 11:03:50 +0200	[thread overview]
Message-ID: <20200630090351.1247703-26-armbru@redhat.com> (raw)
In-Reply-To: <20200630090351.1247703-1-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.

bcm2835_peripherals_realize(), fsl_imx25_realize() and
fsl_imx6_realize() are wrong that way: they pass &err to
object_property_set_uint() and object_property_set_bool() without
checking it, and then to sysbus_realize().  Harmless, because the
former can't actually fail here.

Fix by passing &error_abort instead.
