From e2dbb33ad9545de6859747b92556a74a81bed8f5 Mon Sep 17 00:00:00 2001 From: Kazuya Mizuguchi Date: Wed, 30 Sep 2015 15:15:53 +0900 Subject: [PATCH] ravb: Provide dev parameter to DMA API This patch is in preparation for using this driver on arm64 where the implementation of __dma_alloc_coherent fails if a device parameter is not provided.
