From ec2ed8cdbe8b3d24261f0d88eb039e9d71e5d588 Mon Sep 17 00:00:00 2001
From: John Crispin <blogic@openwrt.org>
Date: Thu, 23 May 2013 16:58:12 +0200
Subject: [PATCH 141/164] clocksource: make clocksource_of_init() pass a
device_node pointer
If we look at the clocksources that are OF enabled we will notice, that they
all do a of_find_matching_node() when being called. This patch changes
clocksource_of_init() to always pass the struct device_node pointer to the
init function.
