[ Upstream commit 505ea3ada6 ]
Adding missing indio_dev->dev.of_node references so that, in case multiple
max31856 are present, users can get some clues to being able to distinguish
each of them. While at it, add also the missing parent reference.

then an uninitialized error return 'ret' is returned. Fix this by
adding a default case that ensures -EINVAL is returned for this
specific case.
