See http://www.infradead.org/rpr.html Sender: linux-ide-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-ide@vger.kernel.org Use the dma_set_mask_and_coherent helper to set the DMA mask. Rely on the relatively recent change that setting a larger than required mask will never fail to avoid the need for the boilerplate 32-bit fallback code.
