Subject: [PATCH] iio: dac: ad5380: fix incorrect assignment to val
Date: Thu, 15 Aug 2019 12:58:46 +0100 [thread overview]
Message-ID: <20190815115846.21800-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Currently the pointer val is being incorrectly incremented
instead of the value pointed to by val. Fix this by adding
in the missing * indirection operator.
Addresses-Coverity: ("Unused value")
Fixes: c03f2c536818 ("staging:iio:dac: Add AD5380 driver")
Signed-off-by: Colin Ian King <colin.king@canonical.com>
