Do you mean "makes little sense" ?

Sounds like a good idea.

Acked-by: Guenter Roeck <groeck@chromium.org>

Many dependencies such as the following can probably be simplified or
removed after this patch has been accepted.

depends on THERMAL=y
depends on THERMAL || THERMAL=n
depends on (HWMON && (THERMAL || !THERMAL_OF)) || !HWMON
depends on !(MLXSW_CORE=y && THERMAL=m)
depends on THERMAL || !THERMAL
depends on HWMON=y || HWMON=THERMAL
depends on THERMAL || !THERMAL_OF
