From d09136b27944ead1618b23c6eb03d8f82d6fc731 Mon Sep 17 00:00:00 2001 From: Vasily Khoruzhick Date: Fri, 5 Mar 2010 13:43:46 -0800 Subject: [PATCH] mmc: enable DMA on Ricoh sdhci reader by default This card reader doesn't advertise, however DMA works well. Probably windows SDHCI driver assumes that all readers support DMA and thus we see that bug.
