Hi Vaishali,
Thanks for the patch.

Use resource-managed function devm_led_classdev_register instead
of led_classdev_register to make the error-path simpler.
To be compatible with the change, goto is replaced with direct
return and unneeded label is dropped. Also, remove redundant
cobalt_qube_led_remove.

We can spare more lines by changing this to:
return devm_led_classdev_register(&pdev->dev, &qube_front_led);
You could get rid of retval then, too.
