Subject: [PATCH 4/5] net: sfc: fix return value check in efx_ptp_probe_channel().
Date: Wed, 12 Dec 2012 01:24:53 +0100 [thread overview]
Message-ID: <1355271894-5284-5-git-send-email-tipecaml@gmail.com> (raw)
In-Reply-To: <1355271894-5284-1-git-send-email-tipecaml@gmail.com>
The ptp_clock_register() returns ERR_PTR() and never returns NULL. Replace the
NULL check by a call to IS_ERR().
