Subject: [PATCH 3/8] input: gameport: convert bus code to use dev_groups

The dev_attrs field of struct bus_type is going away soon, dev_groups
should be used instead.  This converts the gameport bus code to use the
correct field.

Dmitry, I can take this through my driver-core tree if you don't want to
take it through yours, just let me know what works best for you.
