From 7c48ed3383bfb2106694807361ec187fe8a4333d Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Thu, 12 Mar 2009 14:31:33 -0700 Subject: [PATCH] mmc: s3cmci: fix s3c2410_dma_config() arguments. The s3cmci driver is calling s3c2410_dma_config with incorrect data for the DCON register. The S3C2410_DCON_HWTRIG is implicit in the channel configuration and the device selection of S3C2410_DCON_CH0_SDI is incorrect as the DMA system may not select channel 0.
