I have not tried anything with libsensors until now..so it will take some time for me. If you can wait, I can happily submit the required patches :-) But, we are changing the thermal framework quite a bit these days. In some time, things should become saner. Until then, we will not remove this #define and keep it as it is. Once that happens, we can take care of removing this #defined code and also patching libsensors. We can do this now also. I know, we are changing things on the thermal side (sysfs attribute names etc..). If we patch libsensors now, then we might have to re-visit again, soon. That's why, I would like to defer this until things settle down on the Thermal side. Let me know what you think. > > Note: if the same device can now be registered as both hwmon and > thermal, we will have to find a way to detect that to avoid duplicate > entries in libsensors. The hwmon sysfs has a 'name' field. We can pass the same string as the first argument of the thermal_zone_device_register() call. This will show up as 'type' attribute under /sys/class/thermal/thermal_zoneX. So, from user space, we can compare these interfaces and thus avoid the duplicates.
