From 5657933dbb6e25feaf5d8df8c88f96cdade693a3 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Fri, 20 Jan 2017 13:04:02 -0800 Subject: treewide: Move dma_ops from struct dev_archdata into struct device Some but not all architectures provide set_dma_ops(). Move dma_ops from struct dev_archdata into struct device such that it becomes possible on all architectures to configure dma_ops per device.
