In short, the `LateLintPass` has access to type information while the
`EarlyLintPass` doesn't. If you don't need access to type information, use the
`EarlyLintPass`. The `EarlyLintPass` is also faster. However, linting speed
hasn't really been a concern with Clippy so far.
In short, the `EarlyLintPass` runs before type checking and

has access to type information. Consider using the `LateLintPass` unless you need
something specific from the `EarlyLintPass`.
Since we don't need type information for checking the function name, we used
`--pass=early` when running the new lint automation and all the imports were
