+ *
+ * This function saves the MALL (SubVP) case for fast validation cases. For fast validation,
+ * there are situations where a shallow copy of the dc->current_state is created for the
+ * validation. In this case we want to save and restore the mall config because we always
+ * teardown subvp at the beginning of validation (and don't attempt to add it back if it's
+ * fast validation). If we don't restore the subvp config in cases of fast validation +
+ * shallow copy of the dc->current_state, the dc->current_state will have a partially
+ * removed subvp state when we did not intend to remove it.
+ *
+ * NOTE: This function ONLY works if the streams are not moved to a different pipe in the
+ *       validation. We don't expect this to happen in fast_validation=1 cases.
