Helper macro for drivers that dont 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.
module_driver(__driver, __register, __unregister, ...);
__driver
driver name
__register
register function for this driver type
__unregister
unregister function for this driver type @...: Additional arguments to be passed to __register and __unregister.
...
variable arguments
Use this macro to construct bus specific macros for registering drivers, and do not use it on its own.
