Subject: [Qemu-devel] [PULL 1/1] target-i386: Remove unused local_err variable
Date: Fri, 25 Nov 2016 19:30:01 -0200	[thread overview]
Message-ID: <1480109401-19470-2-git-send-email-ehabkost@redhat.com> (raw)
In-Reply-To: <1480109401-19470-1-git-send-email-ehabkost@redhat.com>

local_err can never be set to non-NULL. Remove the variable.
