Subject: [PATCH v2 2/2] iio: imu: adis16460: use DEFINE_DEBUGFS_ATTRIBUTE instead of DEFINE_SIMPLE_ATTRIBUTE
Date: Tue, 31 Mar 2020 17:17:31 +0530 [thread overview]
Message-ID: <20200331114732.14739-3-rohitsarkar5398@gmail.com> (raw)
In-Reply-To: <20200331114732.14739-1-rohitsarkar5398@gmail.com>
debugfs_create_file_unsafe does not protect the fops handed to it
against file removal. DEFINE_DEBUGFS_ATTRIBUTE makes the fops aware of
the file lifetime and thus protects it against removal.
