Subject: [PATCH v2 2/9] blackfin: Provide dma_mmap_coherent() and dma_get_sgtable()
Date: Sun, 27 Jan 2013 11:33:21 +0100 [thread overview]
Message-ID: <1359282808-31398-3-git-send-email-geert@linux-m68k.org> (raw)
In-Reply-To: <1359282808-31398-1-git-send-email-geert-Td1EMuHUCqxL1ZNQvxDV9g@public.gmane.org>
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().
