This is just a helper.
commit bab734fcdf2c690371e6749ce484b17653b3cb0e

driver core: add helper macro for platform_driver_probe() boilerplate
For simple modules that contain a single platform_driver without any
additional setup code then ends up being a block of duplicated
boilerplate. This patch adds a new macro,
module_platform_driver_probe(), which replaces the
module_init()/module_exit() registrations with template functions.
This macro use the same idea of module_platform_driver().
This macro is useful to stop the misuse of module_platform_driver() for
removing the platform_driver_probe() boilerplate.
