From 778a785f02ad846446e91dab49331bd7d853c514 Mon Sep 17 00:00:00 2001 From: Thadeu Lima de Souza Cascardo Date: Wed, 11 Jan 2012 09:09:58 +0000 Subject: powerpc/pseries/eeh: Fix crash when error happens during device probe EEH may happen during a PCI driver probe. If the driver is trying to access some register in a loop, the EEH code will try to print the driver name. But the driver pointer in struct pci_dev is not set until probe returns successfully. Use a function to test if the device and the driver pointer is NULL before accessing the driver's name.
