Should be fine, as per include/linux/clk.h:

    #ifdef CONFIG_HAVE_CLK_PREPARE
    int clk_prepare(struct clk *clk);
    int __must_check clk_bulk_prepare(int num_clks,
                                      const struct clk_bulk_data *clks);
    #else
    static inline int clk_prepare(struct clk *clk)
    {
            might_sleep();
            return 0;
    }

    static inline int __must_check
    clk_bulk_prepare(int num_clks, const struct clk_bulk_data *clks)
    {
            might_sleep();
            return 0;
    }
    #endif

when I'm talking to journalists I just say "programmer" or something like that.
