ERC20Permit.constructor(string).name (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#36) shadows:
- ERC20.name() (@openzeppelin/contracts/token/ERC20/ERC20.sol#62-64) (function)
- IERC20Metadata.name() (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#17) (function)

Variable 'ECDSA.tryRecover(bytes32,bytes).r (@openzeppelin/contracts/utils/cryptography/ECDSA.sol#62)' in ECDSA.tryRecover(bytes32,bytes) (@openzeppelin/contracts/utils/cryptography/ECDSA.sol#57-86) potentially used before declaration: r = mload(uint256)(signature + 0x20) (@openzeppelin/contracts/utils/cryptography/ECDSA.sol#79)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#41-60) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#50)
Avoid relying on block.timestamp.
