Subject[PATCH 4.4 046/105] ARM: OMAP2+: Release device node after it is no longer needed.
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Guenter Roeck <linux@roeck-us.net>


[ Upstream commit b92675d998a9fa37fe9e0e35053a95b4a23c158b ]

The device node returned by of_find_node_by_name() needs to be released
after it is no longer needed to avoid a device node leak.
