Subject: [patch 1/2 net-next] mediatek: checking for IS_ERR() instead of NULL

From: Dan Carpenter <[email-masked]>
Date: Tue, 15 Mar 2016 10:18:49 +0300

of_phy_connect() returns NULL on error, it never returns error pointers.

Fixes: 656e705243fd ('net-next: mediatek: add support for MT7623 ethernet')
