Change Details

In linux docs, there is: ``` Note: <nents> must be the number you passed in, not the number of DMA address entries returned. ``` but I think currently nents is equal to orig_nents in linuxkpi. So It's just a trivial fix.

In linux docs, there is: ``` void dma_unmap_sg(struct device *dev, struct scatterlist *sg, int nents, enum dma_data_direction direction) Note: <nents> must be the number you passed in, not the number of DMA address entries returned. ``` but I think currently nents is equal to orig_nents in linuxkpi.
