Subject: [PATCH] net: davicom: Remove redundant assignment to ret
Date: Sun, 25 Apr 2021 18:42:56 +0800 [thread overview]
Message-ID: <1619347376-56140-1-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/davicom/dm9000.c:1527:5: warning: Value stored to
'ret' is never read [clang-analyzer-deadcode.DeadStores].
