Result<T, E> has an `ok()` method that adapts a Result<T,E> into an Option<T>. It's possible to get around this adapter by writing Result<T,E>.map_or(None, Some). This lint is implemented as a new variant of the existing [`option_map_none` lint](https://github.com/rust-lang/rust-clippy/pull/2128)

error: called `map_or(None, Some)` on a `Result` value. This can be done more directly by calling `ok()` instead
