Subject: [PATCH 4.4 20/30] drivers/misc/c2port/c2port-duramar2150.c: checking for NULL instead of IS_ERR()
Date: Mon, 19 Jun 2017 23:20:54 +0800	[thread overview]
Message-ID: <20170619152034.318184540@linuxfoundation.org> (raw)
In-Reply-To: <20170619152033.211450261@linuxfoundation.org>

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 8128a31eaadbcdfa37774bbd28f3f00bac69996a upstream.

c2port_device_register() never returns NULL, it uses error pointers.

Fixes: 65131cd52b9e ("c2port: add c2port support for Eurotech Duramar 2150")
