From ce16294fda230c787ce5c35f61b2f80d14d70a72 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Lothar=20Wa=C3=9Fmann?= Date: Thu, 21 Mar 2013 02:20:11 +0000 Subject: [PATCH] net: ethernet: cpsw: fix erroneous condition in error check MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The error check in cpsw_probe_dt() has an '&&' where an '||' is meant to be. This causes a NULL pointer dereference when incomplet DT data is passed to the driver ('phy_id' property for cpsw_emac1 missing). Signed-off-by: Lothar Waßmann Signed-off-by: David S.
