its not an error but a warning, as the message state. You just need to add public to your function in case is the visibility scope you want to set for that specific function.

function setName(string newName) public ...

visibility and mutability are two parameters you should always specify to avoid any warning for more about visibility and mutability there are four type of visibility 1) public (access from anywhere) 2) private(cannot be accessed outside the smart contract) 3) external(cannot be called internally) 4) internal(can only be accessed internally within the contract and the contracts drive from it ) for more info http://solidity.readthedocs.io/en/v0.4.21/contracts.html#visibility-and-getters
