> lpc32xx_gpio_probe() registers each gpio chip with

> a chip fails, probe still returns 0, so the driver binds with a chip
> missing and no error is reported.
>
> Check the return value, print an error naming the failing chip and
> return the error code. Chips registered earlier in the loop are devm
> managed and are removed automatically on failure.
