From 646093a29f85630d8efe2aa38fa585d2c3ea2e46 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 19 Jun 2013 10:32:32 +0800 Subject: bcm63xx_enet: fix return value check in bcm_enet_shared_probe() In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
