Thanks!

This imports also appear in two tests. While LintPass is required in the first test, LintArray can be removed. From the second test, both imports can be removed.

tests/ui/lint_without_lint_pass.rs
9:use rustc_lint::{LintArray, LintPass};

tests/ui/default_lint.rs
9:use rustc_lint::{LintArray, LintPass};
