Looking some more into this, since we have this limitation only on
specific replicator on very few QCOM SoCs, rather than having a blanket
workaround for all QCOM, we were thinking it would be better to have
this workaround based on a firmware property something like
"qcom,replicator-loses-context" for those replicators with this
limitation and then set the drvdata->check_idfilter_val based on
this property.
Thanks,
Sai
