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.

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.
