*実装 [#x8daaa3f]
 /*
  * These macros should be used after a dma_map_sg call has been done
  * to get bus addresses of each of the SG entries and their lengths.
  * You should only work with the number of sg entries dma_map_sg
  * returns, or alternatively stop on the first sg_dma_len(sg) which
  * is 0.
