ChangeSet 1.1194, 2003/03/21 16:26:04-08:00, greg at kroah.com
i2c: actually register the i2c client device with the driver core.
We have to initialize the client structure with 0 to keep the
driver core from oopsing.
Now everything is hooked up enough to start removing the i2c sysctl
and proc crud.
