From a9120c33ffbb0b3448d833dae392edc90d6cfac2 Mon Sep 17 00:00:00 2001 From: Per Forlin Date: Fri, 17 Jun 2011 20:14:21 +0200 Subject: mmc: omap_hsmmc: use original sg_len for dma_unmap_sg Don't use the returned sg_len from dma_map_sg() as inparameter to dma_unmap_sg(). Use the original sg_len for both dma_map_sg and dma_unmap_sg according to the documentation in DMA-API.txt.
