Subject: [PATCH] acpi: remove a meaningless null check before debugfs_remove
Date: Sat, 18 Aug 2018 18:49:20 +0800 [thread overview]
Message-ID: <1534589360-64938-1-git-send-email-zhongjiang@huawei.com> (raw)
debugfs_remove has taken null pointer into account. So it is safe
to remove the check before debugfs_remove.
