The attach function pointers haven't actually been called since:
  'commit 3275158fa52a ("parport: remove use of devmodel")'
topped adding entries to the drivers list.

If you're converting a driver, look at the 'match_port' function
pointer instead.

(There are lots of comment references to 'attach' all over, but they
probably need some deeper understanding to check the semantics
to see if they can be replaced by match_port).
