I'm about to send a patch that fixes this.  Greg, if you'd prefer
I re-spin the series (or something else), please let me know.


I did originally have "depends on OF_IRQ" under TC9564_PCI.

However I hit this:

error: recursive dependency detected!
         symbol GENERIC_MSI_IRQ is selected by IRQ_MSI_LIB
         symbol IRQ_MSI_LIB is selected by PCI_XGENE_MSI
         symbol PCI_XGENE_MSI depends on PCI_XGENE
         symbol PCI_XGENE depends on PCI_QUIRKS
         symbol PCI_QUIRKS is selected by TC9564_PCI
         symbol TC9564_PCI depends on OF_IRQ
         symbol OF_IRQ depends on IRQ_DOMAIN
         symbol IRQ_DOMAIN is selected by IRQ_DOMAIN_HIERARCHY
         symbol IRQ_DOMAIN_HIERARCHY is selected by GENERIC_MSI_IRQ

So I removed that dependency and the problem went away.  I'm
sorry I neglected to spend more time troubleshooting that.

So far I have found two options to avoid the recursive dependency:
- Use "select OF_IRQ" rather than "depends on OF_IRQ"
- Use "depends on OF_IRQ" but then use "depends on PCI_QUIRKS"
   rather than "select PCI_QUIRKS"

I like the second one better.

Second one seems better to me too.  ANd a fixup patch is fine.
