Subject: [PATCH 04/18] au1000_eth: pass struct device to DMA API functions
Date:   Fri,  1 Feb 2019 09:47:47 +0100
Message-Id: <20190201084801.10983-5-hch@lst.de>
In-Reply-To: <20190201084801.10983-1-hch@lst.de>
References: <20190201084801.10983-1-hch@lst.de>

Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
