Redundant local variable
Reports an unnecessary local variable that does not make a function more comprehensible:
a local variable that is immediately returned
a local variable that is immediately assigned to another variable and is not used anymore
a local variable that always has the same value as another local variable or parameter.

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
