From bbd7f0a20f76d079199d6d749cb3da07d345bae3 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Wed, 4 Mar 2015 14:57:44 +0100 Subject: [PATCH] mmc: sdhci-spear: Simplify by adding build dependency to CONFIG_OF This driver is used on SoCs which are using CONFIG_OF. By adding a compile dependency in the Kconfig, it enables us to simplify some code.
