[PATCH] PCI: i386/x86_84: disable PCI resource decode on device disable
When a PCI device is disabled via pci_disable_device(), it's still
left decoding its BAR resource ranges even though its driver
will have likely released those regions (and may even have
unloaded). pci_enable_device() already explicitly enables
BAR resource decode for the device being enabled. This patch
disables resource decode for the PCI device being disabled,
making it symmetric with the enable call.
I saw this while doing something else, not because of a
problem report. Still, seems to be the correct thing to do.
