module_driver() 호출 시기

 

insmod / rmmod 시 __register 함수와 __unregister 함수를 자동으로 호출해 준다.

bus에 특정한 mecro를 만들기 위해서 사용해야 하며, 단독으로 사용하면 안된다.

Parameters struct device * devDevice to perform the check on   module_driver(__driver, __register, __unregister, …) Helper macro for drivers that don’t do anything special in module init/exit. This eliminates a lot of boilerplate. Each module may only use this macro once, and calling it replaces module_init() and module_exit(). Parameters __driverdriver name __registerregister function for this driver type __unregisterunregister function for this driver type ...Additional arguments to be passed to __register and __unregister.   Description Use this macro to construct bus specific macros for registering drivers, and do not use it on its own.
