Hi Bjorn and Lorenzo,

PCI drivers use highly similar code block to allocate IRQ domain which
leads to code duplication than expected. This patchset adds a new helper,
pci_host_alloc_intx_irqd(), to avoid that as much as possible.


Changes in v4:
- fix another compile warning reported by Kbuild Robot

Changes in v3:
- rename to pci_host_alloc_intx_irqd and move to probe.c
- fix compile error reported by Kbuild Robot

Changes in v2:
- fix typo and move the code to C file.

Shawn Lin (10):
  PCI: Add pci_host_alloc_intx_irqd() for allocating IRQ domain
  PCI: dra7xx: Use pci_host_alloc_intx_irqd() helper to simplify the
    code
  PCI: keystone-dw: Use pci_host_alloc_intx_irqd() helper to get irq
    domain for INTx
  PCI: aardvark: Use pci_host_alloc_intx_irqd() helper to get irq domain
    for INTx
  PCI: faraday: Use pci_host_alloc_intx_irqd() helper to get irq domain
    for INTx
  PCI: altera: Use pci_host_alloc_intx_irqd() helper to get irq domain
    for INTx
  PCI: mediatek: Use pci_host_alloc_intx_irqd() helper to get irq domain
    for INTx
  PCI: xilinx-nwl: Use pci_host_alloc_intx_irqd() helper to get irq
    domain for INTx
  PCI: xilinx: Use pci_host_alloc_intx_irqd() helper to get irq domain
    for INTx
  PCI: rockchip: Use pci_host_alloc_intx_irqd() helper to get irq domain
    for INTx
