OK, that one is clear. Currently Nut/OS often checks if a function 
pointer is NULL, which has the same result, but produces more code.

But initially Ole suggested a structure containing function pointers, 
quite similar to the NUTDEVICE structure we have now. My question still 
is, how should Nut/OS know about these structure, so it can call its 
initialization functions? Nathan explained the contents of the 
structure, but not its link to the Nut/OS initialization. Correct me if 
I'm wrong.
