From 418a7a7e4f05f36d6e4ab5b8548ea71f0b602140 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 22 May 2017 11:20:18 +0200 Subject: arm: remove arch specific dma_supported implementation And instead wire it up as method for all the dma_map_ops instances. Note that the code seems a little fishy for dmabounce and iommu, but for now I'd like to preserve the existing behavior 1:1.
