Subject[PATCH v2 16/16] thermal/traces: Replace the thermal zone structure parameter with the field value
Date
In the work of the thermal zone device self-encapsulation, let's pass
the field value instead of dereferencing them in the traces which
force us to export publicly the thermal_zone_device structure.

No fonctionnal change intended.
