From 849382948992cc6482c778b1e854c19368b60c05 Mon Sep 17 00:00:00 2001 From: Vasily Khoruzhick Date: Fri, 5 Mar 2010 13:43:46 -0800 Subject: 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.
