From 0eb1645a8daaabab8583333046afac90b5b77fe0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 11 Feb 2019 14:20:04 +0100 Subject: smc911x: pass struct device to DMA API functions 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. Note that smc911x apparently is a PIO chip with an external DMA handshake, and we probably use the wrong device here. But at least it matches the mapping side, which apparently works or at least worked in the not too distant past. Signed-off-by: Christoph Hellwig Signed-off-by: David S.
