This results in a checkpatch warning about the unneeded else. I fixed 
this locally to look like:

+        */
+       if (!hpriv->clks[1]) {
+               clk = clk_get(dev, "refclk");
+               if (IS_ERR(clk)) {
+                       dev_err(dev, "unable to obtain the reference clock");
+                       return -ENODEV;
+               }
+
+               hpriv->clks[1] = clk;
+       }
