This seems fine but doesn't apply against current code but otherwise seems fine.
- if (!IS_ERR(priv->extclk)) {
clk_disable_unprepare(priv->extclk);
clk_put(priv->extclk);
- }
Could use devm_clk_get() for extclk.

My base is 3.11-rc2.

I will do it.

Always submit against where the code will be applied - -next in this case.
