[PATCH] iio: light: fix test for val being not zero or not one.

From: Colin King
Date: Mon Jul 30 2018 - 08:59:25 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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")
