Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: net: thunderx: fix PTP device ref leak in nicvf_probe() cavium_ptp_get() acquires a reference to the PTP PCI device through pci_get_device(). If any initialization step fails after cavium_ptp_get(), the PTP PCI device reference is leaked. Add a common error path to release the PTP reference before returning from probe failures.
