From: Pranjal Ramajor Asha Kanojiya <quic_pkanojiy@xxxxxxxxxxx> Only for_each_sgtable_dma_sg() should be used to walk through a SG table to grab correct bus address and length pair after calling DMA MAP API on a SG table as DMA MAP APIs updates the SG table and for_each_sgtable_sg() walks through the original SG table.
