Subject: [PATCH] ext4: Remove redundant assignment to error
Date:   Thu, 29 Apr 2021 18:16:49 +0800
Message-Id: <1619691409-83160-1-git-send-email-jiapeng.chong@linux.alibaba.com>
Precedence: bulk

Variable error is set to zero but this value is never read as it's not
used later on, hence it is a redundant assignment and can be removed.

Cleans up the following clang-analyzer warning:

fs/ext4/ioctl.c:657:3: warning: Value stored to 'error' is never read
[clang-analyzer-deadcode.DeadStores].
