Re: [PATCH] fpga: zynq-fpga: use sgtable-based scatterlist wrappers

Use common wrappers operating directly on the struct sg_table objects to fix incorrect use of statterlists related calls. dma_unmap_sg() function has to be called with the number of elements originally passed to the dma_map_sg() function, not the one returned in sgtable's nents.
