Subject: [PATCH] media: imx7-mipi-csis: Add the missed v4l2_async_notifier_cleanup in remove
Date:   Mon,  9 Dec 2019 16:58:28 +0800
Message-Id: <20191209085828.16183-1-hslester96@gmail.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

All drivers in imx call v4l2_async_notifier_cleanup() after unregistering
the notifier except this driver.
This should be a miss and we need to add the call to fix it.
