Just to be clear that topology should not be used to enable/disable loopback. Topology should only be used to add the protected kcontrol. This patch does not make this clear in commit message or in token name.
Now the token is only used for adding the kcontrol. The name seems to be misleading. Will refine it and send a V2.
Thanks Xiuli
