Subject: [patch 02/28] I2O: remove i2o_device_class
Content-Disposition: inline; filename=i2o-remove-class.patch
Content-Type: text/plain; charset=US-ASCII
Content-Transfer-Encoding: 7bit

I2O: cleanup - remove i2o_device_class

I2O devices reside on their own bus so there should be no reason
to also have i2c_device class that mirros i2o bus.
