The RX51/Nokia n900 uses the legacy GPIO header to convert a GPIO back to the global GPIO numberspace and then the jack using it in the snd_soc_jack_add_gpios() call immediately looks up the corresponding descriptor again.
The snd_soc_jack_add_gpios() handles GPIOs passed with devices just fine: pass in the device instead, and rename the GPIO to match the property in the device tree, and it should work all the same but without all the trouble.
