Subject: mfd: syscon: Add missing struct device_node declaration
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=5fb1c2dd8f9e9f3fd4ecbaefc75b83ab0ec40cfa;p=linux-edison.git

mfd: syscon: Add missing struct device_node declaration

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.
