Subject: [PATCH 10/14] drm/bochs: drop unused gpu_addr arg from bochs_bo_pin()
Date:   Wed, 19 Dec 2018 12:51:23 +0100
Message-Id: <20181219115127.31359-11-kraxel@redhat.com>

References: <20181219115127.31359-1-kraxel@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

It's always NULL, so just remove it.
