From 63b870f149cdcd253ae8da88d8b5a0b43a68965c Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Thu, 17 Nov 2011 01:19:11 +0900 Subject: ARM: EXYNOS: remove exynos4_scu_enable() The exynos4_scu_enable() is a duplication of scu_enable(). Since commit '26a527e ARM: 7100/1: smp_scu: remove __init annotation from scu_enable()' makes scu_enable() available for non-init codes, exynos can directly call scu_enable() and save exynos4_scu_enable() now.
