irq_alloc_descs - allocate and initialize a range of irq descriptors : Allocate for specific irq number if irq >= 0 : Start the search from this irq number : Number of consecutive irqs to allocate. : Preferred node on which the irq descriptor should be allocated : Owning module (can be NULL)
Returns the first irq number or error code
