cpts_of_mux_clk_setup() obtains refclk_np with of_get_child_by_name() and only drops that reference on the error path. of_clk_add_hw_provider() takes its own reference through of_node_get(), which of_clk_del_provider() releases later, so the reference taken by of_get_child_by_name() is leaked when the mux clock is registered successfully. Drop the caller's reference once the provider has been registered and its devm cleanup action is in place.
