Subject: [PATCH] cxgb4: Remove redundant assignment to ret
Date: Sun, 25 Apr 2021 18:37:03 +0800 [thread overview]
Message-ID: <1619347023-49996-1-git-send-email-jiapeng.chong@linux.alibaba.com> (raw)
Variable ret is set to zero but this value is never read as it is
overwritten with a new value later on, hence it is a redundant
assignment and can be removed.
Cleans up the following clang-analyzer warning:
drivers/net/ethernet/chelsio/cxgb4/t4_hw.c:3830:2: warning: Value stored
to 'ret' is never read [clang-analyzer-deadcode.DeadStores].
Reported-by: Abaci Robot <abaci@linux.alibaba.com>
