4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gustavo A. R. Silva <gust...@embeddedor.com>
commit c5b974bee9d2ceae4c441ae5a01e498c2674e100 upstream.
The IIO_CHAN_INFO_LOW_PASS_FILTER_3DB_FREQUENCY case is missing a
return and will fall through to the default case and errorenously
return -EINVAL.
Fix this by adding in missing *return ret*.
Fixes: 626f971b5b07 ("staging:iio:accel:sca3000 Add write support to the low
pass filter control")
