Input: gpio_keys_polled - suppress deferred probe error for gpio
[ Upstream commit 963465a33141d0d52338e77f80fe543d2c9dc053 ]
On a PC Engines APU our admins are faced with:
$ dmesg | grep -c "gpio-keys-polled gpio-keys-polled: unable to claim gpio 0, err=-517"
261
Such a message always appears when e.g. a new USB device is plugged in.
Suppress this message which considerably clutters the kernel log for
EPROBE_DEFER (i.e. -517).
