[cset] Fix mouse wheel direction in psmouse.c

[Vojtech Pavlik]

Hi!

You can import this changeset into BK by piping this whole message to:
'| bk receive [path to repository]' or apply the patch as usual.
'bk pull http://linux-input.bkbits.net:8080/linux-input' should also
work.

===================================================================

ChangeSet@1.447, 2002-07-25 16:08:56+02:00, [e-mail]
  Because the Linux Input core follows the USB HID standard where it
  comes to directions of movement and rotation, a mouse wheel should
  be positive where it "rotates forward, away from the user". We had
  the opposite in psmouse.c. Fixed this.
