    Empty line is not really needed here, don't you think?

   Hm, can PTR_ERR() be called on non-error pointers? Seems so...

+
+	if (!IS_ERR(phy)) {

+		if (ret) {
+			dev_err(&pdev->dev, "unable to init phy: %d\n", ret);
+			goto err_clk;
  		}
+
+		data->phy = phy;
  	}

Shouldn't this come first instead, with the above PTR_ERR() condition in
the *else* branch?

WBR, Sergei
