Subject: [PATCH 3.16 011/129] clk: kirkwood: fix refcount leak in
kirkwood_clk_init()
3.16.70-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Yangtao Li <tiny.windzz@...il.com>
commit e7beeab9c61591cd0e690d8733d534c3f4278ff8 upstream.
The of_find_compatible_node() returns a node pointer with refcount
incremented, but there is the lack of use of the of_node_put() when
done. Add the missing of_node_put() to release the refcount.
