[PATCH 4.9 248/310] cpuidle: dt: Add missing of_node_put()

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

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

From: Christophe Jaillet <christophe.jaillet@xxxxxxxxxx>


[ Upstream commit b2cdd8e1b54849477a32d820acc2e87828a38f3d ]

'of_node_put()' should be called on pointer returned by
'of_parse_phandle()' when done. In this function this is done in all path
except this 'continue', so add it.
