Someone recently asked on a mailing list (unfortunately I can't recall
which one) if drivers should release irqs over suspend.

The answer was more-or-less that drivers are not expected to do that and it
really is not recommended.  In fact, we do the whole suspend_device_irqs()
thing, because the drivers are expected not to do that.

Best,
Rafael
