[PATCH] iio: dac: remove redundant variable 'shift'

From: Colin King
Date: Mon Jul 02 2018 - 06:24:47 EST


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

Variable shift is being assigned but is never used hence it is
redundant and can be removed.

Cleans up two clang warnings:
warning: variable âshiftâ set but not used [-Wunused-but-set-variable]
