Introduce the module_comedi_driver macro which is a convenience macro for comedi driver modules similar to module_platform_driver. It is intended to be used by drivers where the init/exit section does nothing but register/unregister the comedi driver. By using this macro it is possible to eliminate a few lines of boilerplate code per comedi driver.
