Subject: ARM: OMAP2+: Release device node after it is no longer needed.
From: Guenter Roeck <linux@xxxxxxxxxxxx>
[ 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.
