Subject: [PATCH 08/42] thermal/hwmon: Use the right device for
 devm_thermal_add_hwmon_sysfs()

The devres variant of thermal_add_hwmon_sysfs() only takes the thermal
zone structure pointer as parameter.

Actually, it uses the tz->device to add it in the devres list.

It is preferable to use the device registering the thermal zone
instead of the thermal zone device itself. That prevents the driver
accessing the thermal zone structure internals and it is from my POV
more correct regarding how devm_ is used.

[skipped imx thermal which did not apply cleanly and irrelevant on
mediatek target]
