Well, that test only makes sure that input/output is actually working on the hardware level, but it also makes sure that the GPIOs are numbered correctly. If you want, just put a printk(... offset) in msm_gpio_get() and read from a GPIO that you know you have access to, and make sure the 'offset' is correct. Then try reading from a GPIO that you don't have access to, and make sure you get a failure before msm_gpio_get() is called.
