From f3a6eaaee40b6db5c0b7c7c0ce6ab0f242a8e6ef Mon Sep 17 00:00:00 2001 From: zhangqing Date: Mon, 4 May 2015 09:34:14 +0800 Subject: [PATCH] rk3288: pmic: ricoh619: modify ricoh619_device_shutdown to syscore_shutdown. ricoh619_device_shutdown is earlier than syscore_shutdown. So PMIC use syscore_shutdown is safer.
