Michael Ellerman 7fe3730de7 MSI: arch must connect the irq and the msi_desc ... set_irq_msi() currently connects an irq_desc to an msi_desc. The archs call it at some point in their setup routine, and then the generic code sets up the reverse mapping from the msi_desc back to the irq. set_irq_msi() should do both connections, making it the one and only call required to connect an irq with it's MSI desc and vice versa. The arch code MUST call set_irq_msi(), and it must do so only once it's sure it's not going to fail the irq allocation. Given that there's no need for the arch to return the irq anymore, the return value from the arch setup routine just becomes 0 for success and anything else for failure.
