Markus Pargmann 76f439df50 regulator: Add ena_gpio_initialized to regulator_config ... Most drivers do not set the ena_gpio field of struct regulator_config before passing it to the regulator core. This is fine as long as the gpio identifier that is passed is a positive integer. But the gpio identifier 0 is also valid. So we are not able to decide wether we got a real gpio identifier or not based on a 0 in ena_gpio. To be able to decide if it is a valid gpio that got passed, this patch adds a ena_gpio_initialized field that should be set if was initialized with a correct value, either a gpio >= 0 or a negative error number. The core then checks if ena_gpio or ena_gpio_initialized before handling it as a gpio. This way we maintain backwards compatibility and fix the behaviour for gpio number 0.
