[PATCH 4.14 291/343] iio: dac: ad5380: fix incorrect assignment to val

[Greg Kroah-Hartman]

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

[ 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")
