    Subject[PATCH] dmaengine: care sd_dma_address/len in dmaengine_prep_slave_single()
    dmaengine_prep_slave_single() is helper macro of dmaengine.
    But it doesn't have sg_dma_address/len() settings which are required.
    And it used void *buf in parameter, but it should be dma_addr_t.
    This patch fixes up it.
