3.8.13.18 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Aristeu Rozanski <[email protected]> commit 90ed4988b8c030d65b41b7d13140e9376dc6ec5a upstream. In case the device 0, function 1 is not found using pci_get_device(), pci_scan_single_device() will be used but, differently than pci_get_device(), it allocates a pci_dev but doesn't does bump the usage count on the pci_dev and after few module removals and loads the pci_dev will be freed.
