[U-Boot] [PATCH v2 03/22] stm32: gpio_get_value: always return 0 or 1

Some functions using the GPIO-interface depend on gpio_get_value to return 0 or 1, while the stm32 driver returned 0 or "something not zero". This patch corrects this behaviour. --- drivers/gpio/stm32_gpio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
