Re: [PATCH v17 2/6] soc: qcom: rpmh: Update dirty flag only when data changes

> Currently rpmh ctrlr dirty flag is set for all cases regardless of data
> is really changed or not. Add changes to update dirty flag when data is
> changed to newer values. Update dirty flag everytime when data in batch
> cache is updated since rpmh_flush() may get invoked from any CPU instead
> of only last CPU going to low power mode.
> 
> Also move dirty flag updates to happen from within cache_lock and remove
> unnecessary INIT_LIST_HEAD() call and a default case from switch.
