I'm not sure I understood the comment.
After this change we will have

static int gpiodev_add_to_list(struct gpio_device *gdev)
static void gpiodev_release(struct device *dev)

There are also gpio_device_*() I have noticed, so may be these should be
actually in that namespace?

And we have

static int gpiochip_setup_dev(struct gpio_device *gdev)
static void gpiolib_dbg_show(struct seq_file *s, struct gpio_device *gdev)

That said, what do you think is the best to make this more consistent?
