Thanks for the review!

I wouldn't do it instead of disabling the thermal zone, a TZ without a
sensor doesn't seem very useful.
IIUC the thermistor nodes would need to be deleted, not disabled.
Currently the nodes don't have labels, so either the labels would need
to be added, or the deletion would have to look something like this:
&pm6150_adc {
/delete-node/ charger-thermistor@4f;
};
&pm6150_adc_tm {
/delete-node/ charger-thermistor@0;
};
If the change is done for Lazor it should also be done for PomPom and
CoachZ.
I don't see a strong need to delete the ADC nodes with the clutter it
adds, but I'm open to it if you prefer :)
