Hi!

From: Viresh Kumar <viresh.kumar@...>

commit d54974c2513f487e9e70fbdc79c5da51c53e23da upstream.

OPP core has got almost everything now to manage device's OPP
transitions, the only thing left is device's clk. Get that as well.

@@ -620,6 +622,15 @@ static struct device_opp *_add_device_opp(struct device *dev)
of_node_put(np);
}

+ /* Find clk for the device */
+ dev_opp->clk = clk_get(dev, NULL);
+ if (IS_ERR(dev_opp->clk)) {
+ ret = PTR_ERR(dev_opp->clk);
+ if (ret != -EPROBE_DEFER)
+ dev_dbg(dev, "%s: Couldn't find clock: %d\n", __func__,
+ ret);
+ }
+

Can you double check this piece? In case of clk_get() returning
EPROBE_DEFER, I'd expect this code to return it to the callers,
without continuing initialization.

Best regards,
Pavel
