iio: dac: ti-dac5571 remove redundant variable 'shift'
Variable shift is being assigned but is never used hence it is redundant and can be removed. Cleans up two clang warnings: warning: variable ‘shift’ set but not used [-Wunused-but-set-variable] Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Sean Nyekjaer <sean.nyekjaer@prevas.dk> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
