From a535bb801036268c3d057d7584e9c8f35f69aad4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 27 Aug 2017 10:22:48 +0200 Subject: unicore32: make dma_cache_sync a no-op unicore32 does not implement DMA_ATTR_NON_CONSISTENT allocations, so it doesn't make any sense to do any work in dma_cache_sync given that it must be a no-op when dma_alloc_attrs returns coherent memory.
