Please read the documentation for pci_get_device() for the fact that you
now have a reference to the pci device. You need to properly drop it
when finished.
Please change this patch to do that properly and I will be glad to apply
it.

hmm... I guess that a pci_dev_put() call is lacking if it has been found.
