Subject: [PATCH 4.4 022/183] clk: qoriq: fix refcount leak in clockgen_init()

From: Yangtao Li <tiny.windzz@...il.com>

[ Upstream commit 70af6c5b5270e8101f318c4b69cc98a726edfab9 ]

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.
