The driver uses irq_set_affinity_hint() to: - Set the affinity_hint which is consumed by the userspace for distributing the interrupts - Enforce affinity As per commit 352f58b0d9f2 ("net-next/hinic: Set Rxq irq to specific cpu for NUMA"), the hinic driver enforces its own affinity to bind IRQs to the local NUMA node. However, irq_set_affinity_hint() applying the provided cpumask as an affinity for the interrupt 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_set_affinity_and_hint() that applies the affinity and updates the affinity_hint pointer. Also, use irq_update_affinity() when only affinity_hint needs to be updated.
