driver core: move device->knode_class to device_private
As the description of struct device_private says, it stores data which is private to driver core. And it already has similar fields like: knode_parent, knode_driver, knode_driver and knode_bus. This look it is more proper to put knode_class together with those fields to make it private to driver core. This patch move device->knode_class to device_private to make it comply with code convention. Signed-off-by: Wei Yang <richardw.yang@linux.intel.com> Reviewed-by: Rafael J.
