Having an abstraction layer for a single client driver does seem a bit pointless. It would become more pointful if other client drivers were to pop up. Hence an option would be to merge an IOC4-specific driver which just does what you need, no abstraction layer. If someone later comes up with a requirement for a driver for similar-looking hardware then we can resurrect the abstraction layer at that stage. - 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/
