Subject: [PATCH] iio:chemical:sps30 Suppress some switch fallthrough warnings.

Message-ID: <20190209193934.64038cf4@archlinux> (raw)

Fixes warnings reported on linux-next but marking one path
and adding an explicit return in the other.

I'd like to get this one into linux-next fairly quick so it anyone
has time to do a quick sanity check it would be much appreciated!
