From eed8812387e201e158059fe6fb908f8a662084dd Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Thu, 31 Jan 2013 09:26:06 -0600 Subject: ARM: scu: add empty scu_enable for !CONFIG_SMP Add an empty version of scu_enable for !SMP builds. This fixes compile error for highbank suspend code on !SMP builds.

Since we are only dealing with the cpu we are running on, the cluster id should not ever be needed.
