The GPIO controller is configured as non-sleeping but it uses generic
pinctrl helpers which use a mutex for synchronization. This will cause
lockdep splats when used together with shared GPIOs going through the
GPIO shared proxy driver.
BTW it is a very *welcome* side-effect of the new shared GPIO rework
that it just happens to find these old bugs, I'm very pleased with this :)
