    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().
