That isn't where you are supposed to look for hwmon attributes.

This is also not the correct location.

You should be looking in /sys/class/hwmon/hwmonX/.

There will be a name attribute either in /sys/class/hwmon/hwmonX/name
or in /sys/class/hwmon/hwmonX/device/name. For coretemp, the value
reported in the name attribute will be 'coretemp'. This defines the
directory where the actual sensor attributes will be located.

A better approach might be to use libsensors instead of directly
accessing attributes.

To give you the background, hwmon attributes are in the process of
being moved from the parent device to the hwmon device, or from
/sys/class/hwmon/hwmonX/device/ to /sys/class/hwmon/hwmonX/,
as part of an effort to streamline the code and make it more
consistent and maintainable.
