Subject: [PATCH 4.9 20/46] clk: fixed-factor: fix of_node_get-put imbalance

4.9-stable review patch.  If anyone has any objections, please let me know.

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

[ Upstream commit f98e8a572bddbf27032114127d2fcc78fa5e6a9d ]

When the fixed factor clock is created by devicetree,
of_clk_add_provider is called.  Add a call to
of_clk_del_provider in the remove function to balance
it out.
