There's no "i2c web site". And no, I'm not breaking people's setup for fun. The drivers in question are small, I don't care that much if they stick around. If we can remove them (as is the case for i2c-ixp4xx), great, let's go, but if not, there's really no reason to make gratuitous trouble. The patch I have in my tree now removes i2c-ixp4xx and leaves i2c-ixp2000 and scx200_i2c alone. They can always be removed later if the respective platforms are updated to use the generic GPIO layer. -- Jean Delvare - 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/
