From 597c854974db20eebe87e91df0d12daaefabf525 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Fri, 22 Jun 2012 20:41:10 +0530 Subject: [PATCH] dma: tegra: use sg_dma_address() for getting dma buffer address Use the sg_dma_address() to get the segment buffer address for DMA transfer in place of sg_phys() which returns the physical address of an sg entry. The sg_dma_address() returns the correct buffer memory address for DMA transfer.
