Instead of passing the pointer to the container structure just
pass the input device here. This saves a dereference in the fast
path.

This causes compile errors as you need pwrkey->pwr in remove() to
unregister input device. I'll fix it up.
Ah sorry. I forgot to send the patch before this that converts it
to devm.

 	err = devm_request_irq(&pdev->dev, key_press_irq, pwrkey_press_irq,
-		IRQF_TRIGGER_RISING, "pmic8xxx_pwrkey_press", pwrkey);
+		IRQF_TRIGGER_RISING, "pmic8xxx_pwrkey_press", pwr);
As you can see here because this driver isn't currently using
devm_request_irq().
