I know the patch has already been applied, but this is weird: I just
checked the datasheet again, and it really says this pin is a "gpo".
I'll try to get some more information.
Best regards,

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.
