Subject: [Qemu-devel] [PATCH v3 05/13] raven: Mark use of hw_error() in realize() FIXME
Date: Thu, 17 Dec 2015 17:35:13 +0100	[thread overview]
Message-ID: <1450370121-5768-6-git-send-email-armbru@redhat.com> (raw)
In-Reply-To: <1450370121-5768-1-git-send-email-armbru@redhat.com>

Device realize() methods aren't supposed to call hw_error(), they
should set an error and fail cleanly.  Blindly doing that would be
easy enough, but then realize() would fail without undoing its side
effects.  Just mark it FIXME for now.
