I was thinking we should return IRQ_HANDLED still, but then I guess
failing to clear the irq be treated as a spurious irq so that if we fail
enough times we'll shut off the irq at the irqchip. Things are going bad
if the write fails.
Here bit confusing. Could You please suggest How to go ahead on this?
