Anyway, wouldn't be easier/better to use misc.c functionality here
(misc_register() et al.)?
OTP (one time programmable) memory are not registers, they are small blocks
(8k bytes) of non violate on chip memory, for storing things that you don't
want other people to look at via a PCB level probe. (like keys), or things
that are just helpful - like MAC addresses.
Sorry, misc_register() allows you to get rid of the chrdev initialization
including class creation. Maybe I'm not understanding what you are trying to
explain me?
