#143 Calculator.cc:3025: possible bad if test ?

[dcb]

Calculator.cc:3025:42: warning: comparison of constant 'SUBTYPE_DATA_SET' (2) with expression of type 'bool' is always false [-Wtautological-constant-out-of-range-compare]

Source code is

        if(item->subtype() == item->subtype() == SUBTYPE_DATA_SET) return addDataSet((DataSet*) item, force);

Suggest new code

        if(item->subtype() == SUBTYPE_DATA_SET) return addDataSet((DataSet*) item, force);
