Some systems are reporting the following log message during driver unload or system shutdown: ics_rtas_set_affinity: No online cpus in the mask A prior commit introduced the writing of an empty affinity mask in calls to irq_set_affinity_hint() when disabling interrupts or when there are no remaining online cpus to service an eq interrupt. At least some ppc64 systems are checking whether affinity masks are empty or not. Fix: Do not call irq_set_affinity_hint() with an empty cpu mask.
