I was actually looking at this a few days back and thought I remembered
this being handled in the core now. There was some discussion about this
back in January (?) as far as I remember. I just verified that indeed
there is code in the driver core code to do this. See commit:

	ab78029ecc347debbd737f06688d788bd9d60c1d  drivers/pinctrl: grab default handles from device core

Are you sure this is really necessary in the driver?
