Remove module * parameter from class_create() (#222)

Browse Source 
From v6.4, class_create() does not have module *
See commit 11ba11 :
> driver core: class: remove module * from class_create()
> 
> The module pointer in class_create() never actually did anything,
> and it shouldn't have been requred to be set as a parameter even
> if it did something.  So just remove it and fix up all callers of the
> function in the kernel tree at the same time.
