    Subject[PATCH] mac8390: change an error return code and some cleanup, take 3

    Change an error return code from -EAGAIN to -EBUSY since the former is
    misleading.

    Nubus slots are geographically addressed and their irqs are equally
    inflexible. -EAGAIN is misleading because retrying will not help fix
    whatever bug it was that made the irq unavailable.

    Also promote the log message. Likewise some other KERN_INFO log messages.
