Do you really need the GPIOD_FLAGS_BIT_NONEXCLUSIVE flag here?
I don't think so, but describe what usecase you have that warrants this
being claimed twice. Normally that is just needed when you let the
regulator core handle enablement of a regulator over GPIO, i.e.
ena_gpiod in struct regulator_config.

If you really need this we should add a public API to gpiolib and not
create custom APIs.
Just make a patch adding
int gpiod_to_offset(struct gpio_desc *d);
to the public gpiolib API in include/linux/gpio/consumer.h
and add the code in gpiolib.c to do this trick.
Yours,
Linus Walleij
