struct mspro_block_data	__attribute__
: pointer to a string for the name of this class.
class_create - create a struct class structure : pointer to the module that is to "own" this struct class : the lock_class_key for this class; used by mutex lock debugging 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().
