This is one of the warts of the GPIO API, if you ask me (and probably
others too).
Using a resource without allocating it first is just asking for
trouble. It's one of those
things pinctl was designed to solve... I've been thinking about
spending spare time
sending out patches converting all implicit requests and then removing
the implicit
request, but spare time is limited...

It would be much appreciated. We can make good use of all
help we can get in this area...
