Subject: [PATCH] brcm80211: remove redundant condition check before debugfs_remove_recursive
Date:   Wed, 12 Sep 2018 22:10:12 +0800
Message-ID: <1536761412-24932-1-git-send-email-zhongjiang@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

debugfs_remove_recursive has taken IS_ERR_OR_NULL into account. So just
remove the condition check before debugfs_remove_recursive.
