From 1e96e93a3569fd7a4d3199d9d912345ad3b8ce4c Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 30 Jul 2018 13:59:18 +0100 Subject: [PATCH] iio: light: si1133 fix test for val being not zero or not one. 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.
