Looks good.

We probably may also want to move definition of struct gpio into
include/linux/gpio.h to make things like this work as well:

static struct gpio some_gpios[] = {

static int some_init_function(void)
	/* ... */

	gpio_request_array(some_gpios, ARRAY_SIZE(some_gpios));

	/* ... */

These gpio_request_one() and gpio_request_array() are quite handy, so I
suppose more and more drivers will use it as we go...

Best regards,
