The history of drivers/misc/carma/carma-fpga.c will show you the code
changes necessary. Specifically, these two commits perform the
conversion:
493340207 carma-fpga: Missed switch from of_register_platform_driver()
b00e126ff MISC: convert drivers/misc/* to use module_platform_driver()
Hope it helps,
Ira
