Subject: [PATCH] mac80211: Remove redundant assignment to ret
Date: Fri, 30 Apr 2021 17:21:23 +0800 [thread overview]
Message-ID: <1619774483-116805-1-git-send-email-yang.lee@linux.alibaba.com> (raw)
Variable 'ret' is set to -ENODEV 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.
Clean up the following clang-analyzer warning:
net/mac80211/debugfs_netdev.c:60:2: warning: Value stored to 'ret' is
never read [clang-analyzer-deadcode.DeadStores]
Reported-by: Abaci Robot <abaci@linux.alibaba.com>
