NAME
       __class_create - create a struct class structure

SYNOPSIS
       struct class * __class_create(struct module * owner, const char * name,
                                     struct lock_class_key * key);

ARGUMENTS
       owner
           pointer to the module that is to “own” this struct class

       name
           pointer to a string for the name of this class.

       key
           the lock_class_key for this class; used by mutex lock debugging

DESCRIPTION
       This is used to create a struct class pointer that can then be used in calls to
       device_create.

       Returns struct class pointer on success, or ERR_PTR on error.

       Note, the pointer created here is to be destroyed when finished by making a call to
       class_destroy.
