Subject: [PATCH 2/8] au1000_eth: pass struct device to DMA API functions
Date: Mon, 11 Feb 2019 14:19:58 +0100 [thread overview]
Message-ID: <20190211132004.29143-3-hch@lst.de> (raw)
In-Reply-To: <20190211132004.29143-1-hch@lst.de>
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.
