Could it be merged? On am335 we no do see ~10 annoying error messages during boot as there now is dependency from pinctrl on this platform.

The gpiochip_add_data() may return -EPROBE_DEFER which is not handled properly by TI GPIO driver and causes unnecessary boot log messages. Hence, add proper deferred probe handling with new dev_err_probe() API.
