Hi!

+ /*
+ * To backward compatibility with old DT, this driver checks the return
+ * value if it's -ENOENT or not.
+ */
+ priv->clks[1] = of_clk_get(dev->of_node, 1);
+ if (PTR_ERR(priv->clks[1]) == -ENOENT)
+ priv->clks[1] = NULL;
+ else if (IS_ERR(priv->clks[1]))
+ return PTR_ERR(priv->clks[1]);

I'd really use temporary variable here.

Something like

if (IS_ERR()) {
err = PTR_ERR();
if (err != -ENOENT)
return err;
priv->clks[1] = NULL;
}

But this is -cip, so no need to fix it here, but consider fixing it in
mainline.
