From 18ab67559736335d743503d92b49129e505e1baf Mon Sep 17 00:00:00 2001 From: Jaehoon Chung Date: Fri, 29 Nov 2013 20:08:57 +0900 Subject: [PATCH] mmc: dw_mmc: remove the exynos specific code in dw-mmc.c dw-mmc.c is the general driver file. So, remove the exynos specific code at dw-mmc.c. Instead, exynos specific cod can be move into exynos-dw_mmc.c.
