From 2436bdcda53ff4abb7897c87fa29ef3de8055344 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 25 Aug 2017 17:13:09 +0200 Subject: dma-coherent: remove the DMA_MEMORY_MAP and DMA_MEMORY_IO flags DMA_MEMORY_IO was never used in the tree, so remove it. That means there is no need for the DMA_MEMORY_MAP flag either now, so remove it as well and change dma_declare_coherent_memory to return a normal errno value.
