From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> [ 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).
