From e144d4edbce67ea269d181f81b9c5ef631743430 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Sun, 20 Jul 2014 15:20:59 +0800 Subject: [PATCH] powerpc/4xx: Fix return value check in hsta_msi_probe() In case of error, the function ioremap() returns NULL not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
