Hi Greg,

thanks for the clarification! However, I'm sorry but I'm still
confused: it's said in Documentation/kbuild/makefiles.txt on section
3.3, that if a module kernel is build from several sources file, we
have to use the module_name-y variable. Maybe a misunderstood the
context of this doc (the example is from in-tree kernel module) ?

hurry anyways, I have a scull driver to implements... :)

Thanks,
