Apart from that, currently the kernel panics some seconds after removing
the pinctrl module because mmc wants to access a gpio. Can this be
prevented somehow? I think pinctrl must not be removed once other
devices use any pin-related things.

pinctrl_unregister doesn't look like it cares about whether or not
there's users left in the system.

Both GPIO and pinctrl has this problem, Johan Hovold has been
looking at fixing the GPIO side of things.

Patches welcome.
