From f69bb511455513a61c25783414240258f13f3371 Mon Sep 17 00:00:00 2001 From: Chander Kashyap <chander.kashyap@linaro.org> Date: Tue, 22 Mar 2011 01:40:50 +0000 Subject: [PATCH] S5P: mmc: Resolved interrupt error during mmc_init Blocksize was hardcoded to 512 bytes. But the blocksize varies depeding on various mmc subsystem commands (between 8 and 512). This hardcoding was resulting in interrupt error during data transfer. It is now calculated based upon the request sent by mmc subsystem.
