My comments about the advantages of using that infrastructure for *early* binding captured the key points ... it's "failfast". For IRQs you're probably on decently firm ground, since it's extremely rare that people not handle request_irq() errors. Remember, I just pointed out that the "late fail" strategy is unusual. That doesn't mean it's wrong ... just it'll be a bit of surprise, some cognitive dissonance to developers picking up a Blackfin project, potentially more error prone. - Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
