Bartosz Golaszewski 69920338f8 gpiolib: sanitize the return value of gpio_chip::request() 
The return value of the request() callback may be propagated to
user-space. If a bad driver returns a positive number, it may confuse
user programs. Tighten the API contract and check for positive numbers
returned by GPIO controllers.
