Comparing the two the former has the advantage that the probe and remove callbacks can live in .init.text and .exit.text respectively. The latter has the advantage that it's a bit easier to use correctly and you can bind/unbind via sysfs and/or hotplug. There are considerations about deprecating module_platform_driver_probe()[1] as very few drivers use it, still less make actually use of the advantages and saving a few bytes isn't as important any more as it was (say) 10 years ago. Given that the drivers below drivers/usb/gadget making use of module_platform_driver_probe() doesn't benefit from the advantages at all (probe and remove are all defined in .text), convert these drivers to module_platform_driver().
