[PATCH 3.16 010/129] clk: armada-370: fix refcount leak in a370_clk_init()

From: Ben Hutchings
Date: Sun Jul 07 2019 - 15:47:40 EST


3.16.70-rc1 review patch. If anyone has any objections, please let me know.

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

From: Yangtao Li <tiny.windzz@xxxxxxxxx>

commit a3c24050bdf70c958a8d98c2823b66ea761e6a31 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.
