Dialyzer issue?

I might need some here here:
```
  def load(user, repo) do
    case Tentacat.Contents.readme(user, repo) do
      {200, data, _response} -> {:ok, data}
      {_, _, errors} -> {:error, errors}
    end
  end
```

dialyzer complains: 
```
Function load/2 has no local return.
```

bugging out here...
