Subject: [PATCH] c2port: checking for NULL instead of IS_ERR()
Date: Wed, 12 Apr 2017 08:33:21 +0000	[thread overview]
Message-ID: <20170412083321.GC3250@mwanda> (raw)

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

Fixes: 65131cd52b9e ("c2port: add c2port support for Eurotech Duramar 2150")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
