Bartosz Golaszewski ba3f1a346b gpiolib: provide gpio_device_find() ... [ Upstream commit cfe102f633 ] gpiochip_find() is wrong and its kernel doc is misleading as the function doesn't return a reference to the gpio_chip but just a raw pointer. The chip itself is not guaranteed to stay alive, in fact it can be deleted at any point. Also: other than GPIO drivers themselves, nobody else has any business accessing gpio_chip structs. Provide a new gpio_device_find() function that returns a real reference to the opaque gpio_device structure that is guaranteed to stay alive for as long as there are active users of it.
