I'm not sure what you mean here. There's no next error message in the code as far as I'm aware. If you mean that I'd rather have something like clk = of_clk_get(cn, 0); if (!IS_ERR(clk)) rate = clk_get_rate(clk); else of_property_read_u32(cn, "clock-frequency", &rate)); if (!rate) pr_err() Then, yes, it makes sense.
