I may be able to - one of the downsides though is that many of these systems had hard-coded scripts which started a getty on the original port - and that kind of makes it difficult to sort out. This kind of change becomes very much one of Linus' "flag days". So I'd suggest that we have a period where the old driver is still available, so at least people can choose to use the old major/minor numbers for a while. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
