From ee17962e249024ebba72acbfe7cf54f8ea5b72f8 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 28 Sep 2009 12:36:18 +0100 Subject: ARM: 5731/2: Fix U300 generic GPIO, remove ifdefs from MMCI v3 The #ifdefs in the MMCI driver were erroneous and just masking a bug in the U300 generic GPIO implementation. This removes the ifdefs and fixes the U300 generic GPIO instead.
