Subject: [PATCH AUTOSEL 4.9 195/251] iio: dac: ad5380: fix incorrect assignment to val
Date: Thu, 16 Jan 2020 12:35:44 -0500 [thread overview]
Message-ID: <20200116173641.22137-155-sashal@kernel.org> (raw)
In-Reply-To: <20200116173641.22137-1-sashal@kernel.org>
From: Colin Ian King <colin.king@canonical.com>
[ Upstream commit b1e18768ef1214c0a8048327918a182cabe09f9d ]
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")
