Subject: [PATCH] notifier-error-inject: use DEFINE_DEBUGFS_ATTRIBUTE to define debugfs fops
Date:   Thu, 31 Oct 2019 20:42:08 +0800
Message-ID: <1572525728-23957-1-git-send-email-zhongjiang@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

It is more clearly to use DEFINE_DEBUGFS_ATTRIBUTE to define debugfs file
operation rather than DEFINE_SIMPLE_ATTRIBUTE.

Meanwhile, debugfs_create_file() in debugfs_create_errno() can be replaced
by debugfs_create_file_unsafe().
