In the Linux kernel, the following vulnerability has been resolved:iommu/vt-d: Fix PCI device refcount leak in has_external_pci()for_each_pci_dev() is implemented by pci_get_device(). The comment ofpci_get_device() says that it will increase the reference count for thereturned pci_dev and also decrease the reference count for the inputpci_dev @from if it is not NULL.If we break for_each_pci_dev() loop with pdev not NULL, we need to callpci_dev_put() to decrease the reference count. Add the missingpci_dev_put() before return true to avoid reference count leak.
