I'll do a patch for the USB-core to ensure that intfdata gets set to NULL on probe failure.Hans, I believe this is a good thing per se, but shouldn't this rather be done in driver core, to guarantee that this hold across all buses?
Alan Stern said exactly the same thing :) And I've just finished a patch doing exactly that. I'll send it to the list right after this email.
