Right, and that's for such special cases (hopefully rare) that we have system_state... Much better than your function pointers I reckon.

It's not like it was timing critical code :-) Cheers, Ben. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
