A double assignment of a variable to itself has been detected. This may be a typo.
Check whether this is correct and edit it or remove the extra assignment.
When used as an expression, an assignment evaluates to the result of the RHS expression. For example, in the assignment

someVar = ...; someOtherVar = someVar;
This can have multiple benefits:
