The comment of\npci_get_device() says that it will increase the reference count for the\nreturned pci_dev and also decrease the reference count for the input\npci_dev @from if it is not NULL.\n\nIf we break for_each_pci_dev() loop with pdev not NULL, we need to call\npci_dev_put() to decrease the reference count.
