From 45680995cd8ccf5eb71a1808eb96408589d37a26 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Fri, 29 Mar 2013 14:41:27 +0800 Subject: ARM: mxs: call mxs_pm_init() as a machine_desc hook The device_initcall is not a friend of multiplatform build. Call mxs_pm_init() as a machine_desc hook instead of device_initcall.
