See http://www.infradead.org/rpr.html Sender: dmaengine-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: dmaengine@vger.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP The DMA API generally relies on a struct device to work properly, and only barely works without one for legacy reasons. Pass the easily available struct device from the platform_device to remedy this.
