From 129dd9677b30a07bb832247dfe8d6089f1ac61a0 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 29 Mar 2009 01:20:18 -0700 Subject: [PATCH] ucc_geth: Fix use-after-of_node_put() in ucc_geth_probe(). We can't put 'mdio' until after we've used it in the fsl_pq_mdio_bus_name() call. Also fix error return values. Signed-off-by: David S.
