Testing shows that the Domex 3191D card never asserts its IRQ. Hence it is non-functional with Linux (worse, the EH bugs in the core driver are fatal but that's a problem for another patch). Perhaps the DT-536 chip needs special setup? I can't find documentation for it. The NetBSD driver uses polling apparently because of this issue. Set host->irq = NO_IRQ so the core driver will prevent targets from disconnecting. Don't request host->irq. Signed-off-by: Finn Thain <fthain@xxxxxxxxxxxxxxxxxxx>
