Subject: [PATCH] mtd: nftl: remove redundant variable nb_erases
Date: Wed, 04 Jul 2018 06:46:09 +0000 [thread overview]
Message-ID: <20180704064609.13369-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Variable nb_erases is being assigned but is never used hence it is
redundant and can be removed.
Cleans up clang warning:
warning: variable 'nb_erases' set but not used [-Wunused-but-set-variable]
Signed-off-by: Colin Ian King <colin.king@canonical.com>
