Subject: [PATCH 0/2] PCI: pci_unignore_hotplug()

I'd kinda like to use pci_ignore_hotplug() for devices in use by a
user via vfio-pci, but the interface seems only partially implemented
since we can only set ignore_hotplug and not clear it.  This adds the
capability to clear the flag and applies it as seems to be appropriate
to the existing users.  I don't have a system with power control for
a radeon or nouveau device, so I'd certainly appreciate testing.  It
seems though that once the device is in D0, we've passed the critical
point where the device could be accidentally unplugged.  Thanks,

Alex
