Ahh, then it is fine.

Applied patches 1-6/9 and the fixed routine looks like this now:

+static int _set_opp_level(struct device *dev, struct opp_table *opp_table,
+                         struct dev_pm_opp *opp)
+{
+       unsigned int level = 0;
+       int ret = 0;
+
+       if (opp) {
+               if (!opp->level)
+                       return 0;
+
+               level = opp->level;
+       }
+
+       /* Request a new performance state through the device's PM domain. */
+       ret = dev_pm_domain_set_performance_state(dev, level);
+       if (ret)
+               dev_err(dev, "Failed to set performance state %u (%d)\n", level,
+                       ret);
+
+       return ret;
+}

Does it look okay now ?
