[PATCH] More i2c driver changes for 2.5.65

[greg@kroah.com (Greg KH)]

ChangeSet 1.1194, 2003/03/21 16:26:04-08:00, greg@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.
