Before it would result in the following when calling it:

Attribute function "save_m2m" with type "Callable[[], None]" does not accept self argument [misc]

ok, done.

Note that it is a method that will only be there when commit=False is used before, but I think that cannot be reflected really.

Context: I think that confusion came from these lines: https://github.com/django/django/blob/8c0886b068ba4e224dd78104b93c9638b860b398/django/forms/models.py#L781-L785

But, this is indeed a instance-level method. So, self is there.
