    I don't agree with this change. NO_IRQ for microblaze, arm and other is -1. BTW:
    For ppc is 0. Using NO_IRQ seems to me reasonable.

    you are including linux/irq.h which include asm/irq.h for all platforms except
    s390. I think that is better to find out where the real problem is instead of
    using any hardcoded value.

    If I look at xuartps_get_port function then you don't even need to initialize it
    to NO_IRQ because if there is no IRQ connected driver is not probed. That's why
    "port->irq = res2->start;" is enough.
    I would suggest to completely remove that line from xuartps_get_port
