From acc7c2e0b73a46122ec370bf8a3aa9f19065d331 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Date: Thu, 15 Jun 2006 12:08:30 -0400 Subject: [PATCH] PCI: fix memory leak in MMCONFIG error path This a bit late (yours patch was posted about a year ago), but a co-worker of spotted part of the code that looks like a memory leak. Looking at the code it seems that pci_mmcfg_config should be free-ed if MMCONFIG is above 4GB.
