We have a special case that the TPDM supports both DSB and CMB dataset. 
In this special case, when we

issue this command to enable timestamp, it will call enable_ts_store 
API, right?

     if (tpdm_has_dsb_dataset(drvdata))
         drvdata->dsb->patt_ts = !!val;

     if (tpdm_has_cmb_dataset(drvdata))
         drvdata->cmb->patt_ts = !!val;

Since this special TPDM supports both DSB and CMB dataset, both DSB 
patt_ts and CMB patt_ts will be set

in this case even if I only configure the file in the DSB directory, right?

This is the problem we have now.
