iio: dac: ad5380: fix incorrect assignment to val
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")
