From 3d9939c92efdd4ced672b94994959ca71b141cb8 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 27 May 2013 11:38:41 +0800 Subject: pci: mvebu: fix return value check in mvebu_pcie_probe() In case of error, function of_clk_get_by_name() returns ERR_PTR() never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
