Subject: [PATCH] ath6kl: remove redundant variables netlen, orig_buf, orig_len, dropped and stats
Date: Mon, 9 Jul 2018 14:17:20 +0100 [thread overview]
Message-ID: <20180709131720.6668-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Variables netlen, orig_buf, orig_len, dropped and stats are assigned values
but are never used hence they are redundant and can be removed.
Cleans up clang warnings:
warning: variable 'netlen' set but not used [-Wunused-but-set-variable]
warning: variable 'orig_buf' set but not used [-Wunused-but-set-variable]
warning: variable 'orig_len' set but not used [-Wunused-but-set-variable]
warning: variable 'dropped' set but not used [-Wunused-but-set-variable]
warning: variable 'stats' set but not used [-Wunused-but-set-variable]
