The cleanup_irq() was meant to clear and mask interrupts that were
left enabled in the hardware but there was no interrupt handler
registered for it. Add an error print when it gets invoked.
Why? Don't we get the genirq spurious irq message in this scenario?
Thanks for reviewing the change.
No, there is no existing message printed out in this special case ( IRQ
fired for not registered interrupt).
Ah I see so the irq doesn't have a flow handler? Shouldn't you call
handle_bad_irq() in this case so we get a irq descriptor print?
In such case, the irq number is not valid and there won't be a valid
irq_desc, hence it's not possible to call handle_bad_irq() here.
