Message-Id: <1358073890-3610-2-git-send-email-geert@linux-m68k.org> Date: Sun, 13 Jan 2013 11:44:43 +0100 From: Geert Uytterhoeven <geert@...ux-m68k.org> To: linux-arch@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Geert Uytterhoeven <geert@...ux-m68k.org>, Marek Szyprowski <m.szyprowski@...sung.com>, uclinux-dist-devel@...ckfin.uclinux.org Subject: [PATCH 2/9] blackfin: Provide dma_mmap_coherent() and dma_get_sgtable() blackfin/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 <asm-generic/dma-mapping-common.h>. Blackfin does not use dma_map_ops, hence it should implement them as inline stubs using dma_common_mmap() and dma_common_get_sgtable().
