Julia Lawall d98808a253 drivers/char/ppdev.c: put gotten port value 
parport_find_number() calls parport_get_port() on its result, so there
should be a corresponding call to parport_put_port() before dropping the
reference.  Similar code is found in the function register_device() in the
same file.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

  // <smpl>
  @exists@
  local idexpression struct parport * x;
  expression ra,rr;
  statement S1,S2;
  @@

  x = parport_find_number(...)
  ... when != x = rr
      when any
      when != parport_put_port(x,...)
      when != if (...) { ... parport_put_port(x,...) ...}
  (
  if(<+...x...+>) S1 else S2
  |
  if(...) { ... when != x = ra
       when forall
       when != parport_put_port(x,...)
  *return...;
  }
  )
  // </smpl>
