Subject: [PATCH v2 1/7] thermal/drivers/intel_pch_thermal: Use thermal driver device to write a trace
Date:   Mon, 10 Apr 2023 22:52:59 +0200

The pch_critical() callback accesses the thermal zone device structure
internals, it dereferences the thermal zone struct device and the 'type'.

For the former, the driver related device should be use instead and
for the latter an accessor already exists. Use them instead of
accessing the internals.
