Here you use again the aggregation
I addressed this concern in V6, could you please take a look and let me
know what you think [0].

May I misunderstanding but AFAICS, this patch is setting the mtk_thermal_ops if the sensor id is zero. The get_temp is computing the max temperature in this ops which is what we don't want to do.
