Subject: [Qemu-devel] [PATCH 10/12] kvm: Fix warning from static code analysis
Date: Fri, 14 Sep 2012 09:42:24 +0100	[thread overview]
Message-ID: <1347612146-5407-11-git-send-email-stefanha@gmail.com> (raw)
In-Reply-To: <1347612146-5407-1-git-send-email-stefanha@gmail.com>

From: Stefan Weil <sw@weilnetz.de>

Report from smatch:

kvm-all.c:1373 kvm_init(135) warn:
 variable dereferenced before check 's' (see line 1360)

's' cannot by NULL (it was alloced using g_malloc0), so there is no need
to check it here.
