Subject: [PATCH] staging: comedi: clean up debugging code in #if 0 or 1
Date:   Wed, 23 Dec 2020 10:20:44 +0800
Message-Id: <1608690044-26710-1-git-send-email-chensong_2000@189.cn>
X-Mailer: git-send-email 2.7.4
Precedence: bulk
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

There are a log of "#if 0" or "#if 1" in comedi driver which
cause warning when running checkpatch.pl, they are supposed to
be cleaned up before release.
