The comment of pci_get_device() says that it will increase the reference count for the returned pci_dev and also decrease the reference count for the input pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to call pci_dev_put() to decrease the reference count.

Secondary MMUs don't hold their own references to pages that are mirrored over, so failing to notify them can lead to page use-after-free.
