of_get_gpio() might return -EPROBE_DEFER meaning that the driver providing the gpio isn't ready yet. If that happens for the first gpio the resulting kernel output without this patch is: w1-gpio somename: Failed to parse DT platform somename: Driver w1-gpio requests probe deferral The first message is misleading and so is suppressed with this patch. Further if determining the gpio to switch the external pullup yields -EPROBE_DEFER this error should be passed back to the caller instead of just continuing without pullup.
