This patch introduces the module_serio_driver macro which is a convenience macro for serio driver modules similar to module_platform_driver. It is intended to be used by drivers which init/exit section does nothing but register/unregister the serio driver. By using this macro it is possible to eliminate a few lines of boilerplate code per serio driver.
Based on work done by Lars-Peter Clausen <lars@metafoo.de> for other busses (i2c and spi).
