Input: gpio_keys_polled - suppress deferred probe error for gpio 

[ Upstream commit 963465a331 ]

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).
