[PATCH] clk: ti: fix refcount leak in ti_dt_clocks_register()

From: Yangtao Li
Date: Wed Dec 26 2018 - 08:21:41 EST


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.
