From fc307df88f0d77505c19756d95be66c981c421ea Mon Sep 17 00:00:00 2001 From: Balaji T K Date: Mon, 2 Apr 2012 12:26:47 +0530 Subject: [PATCH] mmc: omap_hsmmc: fix module re-insertion OMAP4 and OMAP3 HSMMC IP registers differ by 0x100 offset. Adding the offset to platform_device resource structure increments the start address for every insmod operation. MMC command fails on re-insertion as module due to incorrect register base. Fix this by updating the ioremap base address only.
