[PATCH 4.19 111/639] clk: kirkwood: fix refcount leak in kirkwood_clk_init()

[Greg Kroah-Hartman]

From: Yangtao Li <tiny.windzz@xxxxxxxxx>

[ Upstream commit e7beeab9c61591cd0e690d8733d534c3f4278ff8 ]

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.
