public static function EntityInlineForm::submitCleanFormState in Inline Entity Form 8

Cleans up the form state for a submitted entity form.

After field_attach_submit() has run and the form has been closed, the form state still contains field data in $form_state->get('field'). Unless that data is removed, the next form with the same #parents (reopened add form, for example) will contain data (i.e. uploaded files) from the previous form.

Parameters

$entity_form: The entity form.

$form_state: The form state of the parent form.
