It's this:

+static int tegra124_cpufreq_probe(struct platform_device *pdev)
+{
[...]
+
+       dfll_clk = of_clk_get_by_name(cpu_dev->of_node, "dfll");
+       if (IS_ERR(dfll_clk)) {
+               ret = PTR_ERR(dfll_clk);
+               goto out_put_cpu_clk;
+       }

This would search for clocks passed via DT, right? Why would we
get EPROBE_DEFER for that? Sorry for the stupid question.

of_clk_get_by_name() can return -EPROBE_DEFER, which will happen if the
clock provider hasn't been registered yet.
