microblaze: Fix sg_dma_len() regression
The commit "asm-generic: add NEED_SG_DMA_LENGTH to define sg_dma_len()" 18e98307de0d746cb0845ebf66535ce2184c25a2 broke microblaze compilation. dma_direct_map_sg() sets sg->dma_length, however microblaze doesn't set NEED_SG_DMA_LENGTH so scatterlist strcutres doesn't include dma_length. sg->dma_length is always equal to sg->length on microblaze. So we don't need to set set dma_length, that is, microblaze can simply use sg->length. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Michal Simek <monstr@monstr.eu>
