Check style incorrectly formatted - Intellij complains

 I get the following two errors when I try to import the checkstyle file into CheckStyle-IDEA plugin. Interestingly mvn target works ok.

- com.puppycrawl.tools.checkstyle.api.CheckstyleException: cannot initialize module TreeWalker - TreeWalker is not allowed as a parent of LineLength Please review 'Parent Module' section for this Check in web documentation if Check is standard.

As per the documentation [1]

• LineLength's parent should be Checker.

Fixing this parent-child relationship, I was able to import the file correctly. Will attach the patch shortly.
