In the event that a client of the rp1-pio driver is probed before it, return -EPROBE_DEFER from pio_open to allow it to be retried. Otherwise, return an error code on error, not a NULL pointer, as that is what clients are expecting. See: raspberrypi#7211 Signed-off-by: Phil Elwell <phil@raspberrypi.com>
