Some devices use 255 as default value of Interrupt Line register, and this maybe causes pdev->irq is set as IRQ_NOTCONNECTED in some scenarios. For example, NVMe controller connects to Intel Volume Management Device (VMD). In this situation, IRQ_NOTCONNECTED means INTx line is not connected, not fault. If bind uio_pci_generic to these devices, uio frame will return -ENOTCONN through request_irq. This patch allows binding uio_pci_generic to device with dev->irq of IRQ_NOTCONNECTED.
