Subject: [PATCH 3/5] c2port: fix return value check in duramar2150_c2port_init().
Date: Wed, 12 Dec 2012 01:24:52 +0100	[thread overview]
Message-ID: <1355271894-5284-4-git-send-email-tipecaml@gmail.com> (raw)
In-Reply-To: <1355271894-5284-1-git-send-email-tipecaml@gmail.com>

The c2port_device_register() function returns ERR_PTR() and never returns NULL,
so the NULL check should be replaced by a call to IS_ERR().
