Subject: [PATCH] iio: dac: remove redundant variable 'shift'
Date: Mon,  2 Jul 2018 11:24:35 +0100	[thread overview]
Message-ID: <20180702102435.16724-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

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>
