Subject: [PATCH 2/9] passthrough/amd: Drop unnecessary lock lookup.
Date: Thu, 12 Sep 2013 13:15:23 +0100 [thread overview]
Message-ID: <1378988130-24172-3-git-send-email-tim@xen.org> (raw)
In-Reply-To: <1378988130-24172-1-git-send-email-tim@xen.org>
The lock's not used for anything, and AFAICT no locking is needed
since the IVRS tables are static after boot.
Coverity CID 1087199
