Actually, I'd been meaning to fix of_gpio_count for quite a while now. The current code uses a stupid algorithm to parse each specifier one at a time and count how many iterations it takes before getting an error. BLECH! A pox on me for being so lazy when I wrote it.
Anyway, your patch here spurred me on to fix it. I've just done so and will post the patch in a few minutes. Please test and let me know if it works for you.
