4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King <colin.k...@canonical.com>
[ Upstream commit c894acc7bf400d039bf740420b22f0b71b7fb504 ]
Ensure that when an invalid value in ret or value is found -EINVAL
is returned. A previous commit broke the way the return error is
being returned and instead caused the return code in ret to be
re-assigned rather than be returned.
Fixes: 5d9854eaea776 ("iio: hid-sensor: Store restore poll and hysteresis on
S3")
