From 063acebaf4795e57fd2c49d712a9179d8bfa9192 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Sun, 27 Jan 2013 09:33:23 +0000 Subject: [PATCH] cris: Provide dma_mmap_coherent() and dma_get_sgtable() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit cris/allmodconfig: drivers/media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_mmap’: drivers/media/v4l2-core/videobuf2-dma-contig.c:204: error: implicit declaration of function ‘dma_mmap_coherent’ drivers/media/v4l2-core/videobuf2-dma-contig.c: In function ‘vb2_dc_get_base_sgt’: drivers/media/v4l2-core/videobuf2-dma-contig.c:387: error: implicit declaration of function ‘dma_get_sgtable’ For architectures using dma_map_ops, dma_mmap_coherent() and dma_get_sgtable() are provided in . Cris does not use dma_map_ops, hence it should implement them as inline stubs using dma_common_mmap() and dma_common_get_sgtable().
