From: Marcel Ziswiler <redacted> 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 <redacted> --- drivers/gpio/gpiolib.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
