Patch 4/5 is "Return the fan speed via sysfs: /sys/devices/temperature/fan_level".

So you are saying that returning the fan speed with a non-hwmon attribute works,
but returning it with a hwmon attribute doesn't ? Not really sure if I understand
your logic. Either fan_level doesn't return the fan speed (or an abstraction of it),
or something in your line of argument is inconsistent.
