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.
