[v2,3/7] thermal/drivers/acpi: Use thermal_zone_device()

Commit Message

Daniel Lezcano April 10, 2023, 8:53 p.m. UTC

In order to get the device associated with the thermal zone, let's use
the wrapper thermal_zone_device() instead of accessing directly the
content of the thermal zone device structure.
