[PATCH] Driver: Adding helper macro for platform_driver boilerplate.

From: Harshal Chaudhari
Date: Sat May 09 2020 - 06:07:42 EST


From: Harshal <harshalchau04@xxxxxxxxx>

For simple module that contain a single platform_driver without any additional setup code then ends up being a block
of duplicated boilerplate.

This patch add a new micro, module_platform_driver(), which replace the module_init()/module_exit() registrations
with template functions.
