Subject: [PATCH] drivers: mcb: use symbol namespaces
Date:   Wed, 16 Oct 2019 12:01:58 +0200
Message-Id: <20191016100158.1400-1-jthumshirn@suse.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Now that we have symbol namespaces, use them in MCB to not pollute the
default namespace with MCB internals.
