Subject: [PATCH] ide-tape: remove redundant variable buffer_size
Date: Mon, 2 Jul 2018 11:00:26 +0100 [thread overview]
Message-ID: <20180702100026.16007-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Variable buffer_size is being assigned but is never used hence it is
redundant and can be removed.
Cleans up clang warning:
warning: variable 'buffer_size' set but not used [-Wunused-but-set-variable]
Signed-off-by: Colin Ian King <colin.king@canonical.com>
