PCI/portdrv: Remove warning about invalid IRQ for hot-added PCIe ports
For hot-added PCIe ports on x86 platforms, we always warned about an invalid IRQ, e.g., pci 0000:00:00.0: device [8086:0e0b] has invalid IRQ; check vendor BIOS This was because we check pci_dev->irq before actually allocating the IRQ for the device, which happens in this path: pcie_port_device_register pci_enable_device pci_enable_device_flags do_pci_enable_device pcibios_enable_device (on x86) pcibios_enable_irq This warning message isn't generated for PCIe ports present at boot time because x86 arch code has called acpi_pci_irq_enable() in pci_acpi_init() for each PCI device for safety.
