From 83bd9243956f30d91851b272988a237999b35b10 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Mon, 15 Dec 2008 15:09:50 +0100 Subject: x86/oprofile: fix pci_dev use count for AMD northbridge devices This patch fixes the PCI device use count for AMD northbridge devices. In case of an IBS LVT initialization failure, the PCI device is released now by calling pci_dev_put(). If there are no initialization errors, the devices are released in pci_get_device() while iterating.
