However, under the hood irq_set_affinity_hint() also applies the provided cpumask (if not NULL) as the affinity for the given interrupt which is an undocumented side effect. To remove this side effect irq_set_affinity_hint() has been marked as deprecated and new interfaces have been introduced. Hence, replace the irq_set_affinity_hint() with the new interface irq_update_affinity_hint() that only updates the affinity_hint pointer.
