From a528721da08a793e0cec6ef6281d404eddd6e27b Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 4 Nov 2011 15:05:24 +0000 Subject: [PATCH] ARM: restart: add restart hook to machine_desc record Add a restart hook to the machine_desc record so we don't have to populate all platforms with init_early methods to initialize the arm_pm_restart function pointer.
