From 7bd7b091429705eb281d60c553cc643aada8045a Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Thu, 29 Sep 2005 00:40:07 -0500 Subject: [PATCH] [PATCH] I2O: remove i2o_device_class 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.
