I don't think tango_msi_probe() is really a "probe" function. It's all part of the tango driver, and it's not claiming a separate piece of hardware. So I would keep the name and structure similar to these: advk_pcie_init_msi_irq_domain() nwl_pcie_init_msi_irq_domain() BTW, those functions use irq_domain_add_linear(), while you are one of the very few callers of irq_domain_create_linear(). Why the difference? If your code does basically the same thing, it's very helpful to me if it *looks* basically the same. > Can I send you a patch series with these changes on Friday? I was planning to ask Linus to pull my branch tomorrow or Friday because I'm going on vacation next week and I don't want to leave right after he pulls it. So the sooner the better. Bjorn
