Subject: [PATCH] iio: light: fix test for val being not zero or not one.
Date: Mon, 30 Jul 2018 12:59:18 +0000 [thread overview]
Message-ID: <20180730125918.7100-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The current check on val always results in true and so the
call to sii1133_update_adcsens never gets called. Fix this check
so it returns with -EINVAL only when val is not zero and not one.
Detected by CoverityScan, CID#1472099 ("Logically dead code")
Fixes: e01e7eaf37d8 ("iio: light: introduce si1133")
