Should we fail to resume if error is returned from 'opp_set_rate'?
'spi_geni_prepare_message' use to fail for any error from
'opp_set_rate' before patch series "Avoid clock setting if not needed".
But now it's possible that 'prepare_message' can return success even
when opp are not at desired state(from previous resume call).
Regards,
Akash
