[PATCH 3/3] PCI: Xilinx NWL PCIe: Fix Error for multi function device for legacy interrupts.

From: Bharat Kumar Gogada
Date: Tue Aug 30 2016 - 06:40:08 EST


PCIe legacy interrupts start at 1, not at 0.
When testing with multi function device "error: hwirq 0x4 is too large for
dummy" error comes.
So adding one addtional interrupt when creating irq domain.
