Subject: [PATCH 3/9] xen/pciback: Check if the device is found instead of blindly assuming so.
Date: Thu, 29 Sep 2011 15:52:45 -0400 [thread overview]
Message-ID: <1317325971-21603-4-git-send-email-konrad.wilk@oracle.com> (raw)
In-Reply-To: <1317325971-21603-1-git-send-email-konrad.wilk@oracle.com>
Just in case it is not found, don't try to dereference it.
