Router.sol: Redundant _token initialization in addLiquiditySingleForMember()

[code423n4]

Handle

hickuphh3

Vulnerability details

Impact

The lines below of the addLiquiditySingleForMember() function

address _token = token;
if(token == address(0)){_token = WBNB;} // Handle BNB -> WBNB

are redundant since _token is not used subsequently. Note that _handleTransferIn() will perform the handling of native BNB transfers.

Recommended Mitigation Steps

The mentioned lines above can be removed.
