Robert Hancock 9f09e78db5 pps: clients: gpio: Propagate return value from pps_gpio_probe ... [ Upstream commit abaca3179b ] If the pps-gpio driver was probed prior to the GPIO device it uses, the devm_gpiod_get call returned an -EPROBE_DEFER error, but pps_gpio_probe replaced that error code with -EINVAL, causing the pps-gpio probe to fail and not be retried later. Propagate the error return value so that deferred probe works properly.
