Subject: [Qemu-devel] [PATCH 1/2] s390x: fix cpu object referrence leak in s390x_new_cpu()
Date: Tue, 17 Oct 2017 15:41:19 +0200	[thread overview]
Message-ID: <1508247680-98800-2-git-send-email-imammedo@redhat.com> (raw)
In-Reply-To: <1508247680-98800-1-git-send-email-imammedo@redhat.com>

object_new() returns cpu with refcnt == 1 and after realize
refcnt == 2*. s390x_new_cpu() as an owner of the first refcnt
should have released it on exit in both cases (on error and
success) to avoid it leaking. Do so for both cases.
