IMO, the simplest way is using probe/remove in struct i2c_driver and use i2c_board_info and i2c_device_id to match it with your device. You do not have to use attach_adapter and detach_adapter. > I have been getting some issue in the SMBus through i2c-core. Do you think > this could be the source of that issue? What kind of issue ?

Please start a new e-mail thread to post your queries. This will help folks who go through this mailing list archive to find out answer to a specific problem. In this case, the original question was "Integer Division on 32 Bit Machines". So it would be easy to find the answer to this if one e-mail thread handled only this or may be some closely related stuff.
