Hence, use the IRQ_WORK_INIT_HARD\nvariant so that with PREEMPT_RT kernels, the IRQ work is processed in\nhardirq context instead of being deferred to a thread which is required\nfor calling generic_handle_irq().\n\nOn non-PREEMPT_RT kernels, both init_irq_work() and IRQ_WORK_INIT_HARD()\nexecute in IRQ context, so this change has no functional impact for\nstandard kernel configurations.\n\n[treding@nvidia.com: miscellaneous cleanups]"
