[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. From: Konrad Rzeszutek <konradr@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
