[ 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")
