Type was assigned in wacom_wireless_work [1] before we moved code
around. It somehow failed to get into wacom_parse_and_register. The
value was only assigned once on stylus interface. It was unnecessary
to assign it again on touch interface since it is a shared value.
Maybe that was the reason it missed its "flight"?

Yeah, wireless is a dynamic connection. We can not tell which tablet
model is going to be connected before it is paired. But, the dongle is
always the same. That's the tricky part.

Aaron tested it. So, your code is safe ;).
