Subject: PCI: Free saved list without holding pci_bus_sem
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1d8a0506f69895b7cfd9d5c4546761c508231a8a;p=thirdparty%2Fkernel%2Flinux.git

PCI: Free saved list without holding pci_bus_sem

Freeing the saved list does not require holding pci_bus_sem, so the
critical section can be made shorter.
