Subject: [PATCH] mfd: syscon: Add missing struct device_node declaration
Date: Mon, 25 Mar 2013 17:56:23 +0100
Message-id: <1364230583-4043-1-git-send-email-s.nawrocki@samsung.com>

syscon.h header uses struct device_node in functions' declarations
without declaring it. This causes compilation warnings like:

include/linux/mfd/syscon.h:20: warning: ‘struct device_node’
declared inside parameter list
include/linux/mfd/syscon.h:20: warning: its scope is only this
definition or declaration, which is probably not what you want

Fix it by adding a forward declaration of struct device_node.
