gpiolib: Fix error return code in gpiolib_dev_init()
Fix to return a negative error code from the error handling case instead of 0, as done elsewhere in this function. Fixes: 4731210c09f5 ("gpiolib: Bind gpio_device to a driver to enable fw_devlink=on by default") Reported-by: Hulk Robot <hulkci@huawei.com> Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>
