Subject: iio: sca3000: Fix missing return in switch
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b86374912fee81fc266355b2a911cbbb92ffff54;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

iio: sca3000: Fix missing return in switch

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*.
