From 0f70e8cea3ac6a765289811c590a16934bf47711 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Wed, 15 Dec 2010 18:50:16 +0100 Subject: dmaengine: at_hdmac: use dma_address to program DMA hardware In atc_prep_slave_sg() function we use dma_address field of scatterlist with sg_dma_address() macro instead of sg_phys(). DMA address is already computed by dma_map_sg() or another mapping function in calling driver.
