Yes, that is. Additionally, some people may be using it for driving specific i2c chips that do not have a driver yet. But they should have written a driver instead, and send it to us too, so since they did not, they are considered bad guys, and we don't care about breaking their toys ;) > And because of that, we shouldn't break the 2.4 user/kernel interface, > right?

Come here Greg, let's shut up together and feel less lonely in our silence ;) Of course you won't shut up, because nothing related to i2c in 2.6 could be done without your so precious help. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
