Yep, exactly. I've seen that in the public docs. It must be a typo,
unless there's something we don't know.

On DNS-327L this pin is wired as a button. Without th patch only
gpio-buttons driver fails probing, but you can still configure the pin
as input via sysfs gpio interface and even read sensible values from it.
If you have a board where this pin is broken out - it's easy to test.
