Subject: [PATCH 3.16.y-ckt 074/168] ARM: mvebu: add missing of_node_put() call in coherency.c

3.16.7-ckt3 -stable review patch.  If anyone has any objections, please let me know.

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

From: Thomas Petazzoni <thomas.petazzoni@...e-electrons.com>

commit 2eb04ae010a8fb165ba7aa56e9aa8e7980887dee upstream.

There is a missing of_node_put() to decrement the device_node
reference counter after a of_find_matching_node() in coherency_init().

Fixes: 501f928e0097 ("ARM: mvebu: add a coherency_available() call")
