Input: serio - add helper macro for serio_driver boilerplate
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 registers/unregisters 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 buses (i2c and spi).
