Make pci_dev_is_disconnected() public so that it can be called from
Intel VT-d driver to quickly fix/workaround the surprise removal
unplug hang issue for those ATS capable devices on PCIe switch downstream
hotplug capable ports.

Beside pci_device_is_present() function, this one has no config space
s/Beside/Unlike/

Beside means 'comparing with' here, perhaps it is not clear enough

or there is syntax error if used here ?



Thanks,

Ethan


space access, so is light enough to optimize the normal pure surprise
removal and safe removal flow.
somehow this paragraph belongs to the patch using it. The 1st paragraph
is sufficient for the reason of exposure.
