Subject: [PATCH] ufs: remove an unneed NULL check on list iterator
Date:   Sat, 19 Mar 2022 12:26:57 +0800
Message-Id: <20220319042657.21835-1-xiam0nd.tong@gmail.com>
Precedence: bulk

The list iterator is always non-NULL so it doesn't need to be checked.
Thus just remove the unnecessary NULL check.
