From: "Gustavo A. R. Silva" <gustavo@xxxxxxxxxxxxxx>
[ Upstream commit c5b974bee9d2ceae4c441ae5a01e498c2674e100 ]
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")
