gpiolib: probe deferral error reporting
Actually report the error code from devm_regulator_get() which may as well just be a probe deferral. This is e.g. what one gets upon booting a Colibri T20: gpiochip_add_data_with_key: GPIOs 0..223 (tegra-gpio) failed to register Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
