    Subject[PATCH 4.19 03/48] of: clk: Make <linux/of_clk.h> self-contained
    Date
    From: Geert Uytterhoeven <geert+renesas@glider.be>

    commit 5df867145f8adad9e5cdf9d67db1fbc0f71351e9 upstream.

    Depending on include order:

    include/linux/of_clk.h:11:45: warning: ‘struct device_node’ declared inside parameter list will not be visible outside of this definition or declaration
    unsigned int of_clk_get_parent_count(struct device_node *np);
    ^~~~~~~~~~~
    include/linux/of_clk.h:12:43: warning: ‘struct device_node’ declared inside parameter list will not be visible outside of this definition or declaration
    const char *of_clk_get_parent_name(struct device_node *np, int index);
    ^~~~~~~~~~~
    include/linux/of_clk.h:13:31: warning: ‘struct of_device_id’ declared inside parameter list will not be visible outside of this definition or declaration
    void of_clk_init(const struct of_device_id *matches);
    ^~~~~~~~~~~~

    Fix this by adding forward declarations for struct device_node and
    struct of_device_id.
