Date: Wed, 15 Dec 2010 18:50:16 +0100 From: Nicolas Ferre <nicolas.ferre@...el.com> To: dan.j.williams@...el.com, linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org, Nicolas Ferre <nicolas.ferre@...el.com> Subject: [PATCH] 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.
