From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christoph Hellwig Date: Mon, 17 Sep 2018 17:10:31 +0000 Subject: [PATCH 9/9] intel-iommu: mark intel_dma_ops static Message-Id: <20180917171031.3853-10-hch@lst.de> List-Id: References: <20180801160252.25629-10-hch@lst.de> In-Reply-To: <20180801160252.25629-10-hch@lst.de> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org ia64 currently explicitly assigns it to dma_ops, but that same work is already done by intel_iommu_init a little later, so we can remove the duplicate assignment and mark the variable static.
