Hi,
any opinion (except typo)?
thermanl => thermal

No #ifdef in C file.

based on your comments this should be enough/right?
#if IS_ENABLED(CONFIG_THERMAL_HWMON)
tzdev->tzp->no_hwmon = false;
ret = devm_thermal_add_hwmon_sysfs(tzdev);
if (ret)
dev_err(&pdev->dev, "error in thermal_add_hwmon_sysfs");
#endif
if yes i send out v2, at least it works on my device
regards Frank

just the following lines should work:
ret = devm_thermal_add_hwmon_sysfs(tzdev);
if (ret)
dev_err(&pdev->dev, "error in thermal_add_hwmon_sysfs");
The no_hwmon usage is a bit fuzzy in the thermal core code.

Maybe add depency in Kconfig? Else we can get undefined symbols on linking

Nope, there are the stubs in thermal_hwmon.h
