Ok, I might miss a general thing here. All I do is add a driver which is loaded via the module_init() mechanism and registers itself for that specific device by name. In the board support file, I add a list of i2c_board_infos by calling i2s_register_board_info() and then the driver is magically instanciated in some lower layer. The question is: how do I access this instance at a later point? Without messing around with static pointers, of course.
