From b0cbeae4944924640bf550b75487729a20204c14 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 21 Nov 2018 18:52:35 +0100 Subject: dma-direct: remove the mapping_error dma_map_ops method The dma-direct code already returns (~(dma_addr_t)0x0) on mapping failures, so we can switch over to returning DMA_MAPPING_ERROR and let the core dma-mapping code handle the rest.
