Subject: [PATCH] iio: dac: ti-dac5571 remove redundant variable 'shift'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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]
