Solve the following python programming problem given the following code:
def save(self, commit = True) : 
    super (ServiceForm, self).save (commit = False) 
    def save_m2m() : 
        opts = self.instance._meta 
        cleaned_data = self.cleaned_data 
        fields = self._meta.fields 
        for f in opts.many_to_many : 
            if (fields and (f.name not in fields)) : 
                continue 
if (f.name in cleaned_data) : 
                if (f.name == 'depends_on') : 
                    self.instance.depends_on.clear () 
                    for service in cleaned_data [f.name] : 
                        Dependency.objects.get_or_create (dependant = self.instance, provider = service) 
else : 
                    f.save_form_data (self.instance, cleaned_data [f.name]) 
if commit : 
        self.instance.save () 
        save_m2m () 
return commit.instance 

    
    

    Fix the buggy line: return commit.instance
