From cda56ac29f2d8288d62978272856884d26e0b47b Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 10 Feb 2009 16:32:33 +0200 Subject: [PATCH] mmc: fix data timeout for SEND_EXT_CSD Commit 0d3e0460f307e84904968aad6cff97bd688583d8 "MMC: CSD and CID timeout values" inadvertently broke the timeout for the MMC command SEND_EXT_CSD. This patch puts it back again. Depending on the characteristics of the controller, this bug may prevent the use of MMC cards.
