Subject: [PATCH] libxc: fix leak in xc_dom_load_hvm_kernel error path
Date: Wed, 3 Feb 2016 11:59:57 +0100	[thread overview]
Message-ID: <1454497197-2134-1-git-send-email-roger.pau@citrix.com> (raw)
In-Reply-To: <1454495951.25207.52.camel@citrix.com>

Error path in xc_dom_load_hvm_kernel needs to use the 'error' label instead
of directly returning. This is needed so the entries local variable is
freed.
