Although dma_map_sg_attrs returns 0 on error and it cannot return a value < 0, the function returns a signed integer. Most of the time, this function is used with a scatterlist structure. This structure uses an unsigned integer for the number of memory. A dma developer that has not read in detail DMA-API.txt, can wrongly return a value < 0 on error. The comment will help the driver developer, and the WARN_ON the dma developer.
