From dc4910d9e93f8cc56b190dd8fc9e789135978216 Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Mon, 20 Jan 2014 15:59:50 +0100 Subject: [PATCH] ARM: mvebu: Fix kernel hang in mvebu_soc_id_init() when of_iomap failed When pci_base is accessed whereas it has not been properly mapped by of_iomap() the kernel hang. The check of this pointer made an improper use of IS_ERR() instead of comparing to NULL. This patch fix this issue.
