I'll prepare a patch for that...
But that doesn't solve my original problem with the hardcoded "ttyGS"...

In u_serial with something like:
- pr_debug("gs_open: ttyGS%d (%p,%p)\n", port->port_num, tty, file);
+ pr_debug("gs_open: %s (%p,%p)\n", dev_name(tty->dev), tty, file);
Or is there a better approach?
What will be a good solution for f_acm/f_obex instead of PREFIX? Or should PREFIX be renamed and used?
Thanks for your help and patience!
