It is inconsistent. Before you used "(!pd)" and "(!pdata)" so maybe
stick to one format?

Can you add short comment why this is needed? I know why but just for
future generations which will wonder: "why do we need to disable the IRQ
while suspending?" :). Especially that this is rather a workaround for
issue in other driver (I2C bus).
