parisc: Provide dummy dma_mmap_coherent() and dma_get_sgtable()
parisc/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>.
Parisc does not use dma_map_ops, hence it should implement them itself.
For now, use dummy implementations that just return -EINVAL, until the
API has been finalized, as it cannot be supported on PA-RISC as-is.
