Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: phy: renesas: rcar-gen2: Fix double of_node_put on phy creation failure for_each_child_of_node_scoped() releases the node reference on scope exit, so the explicit of_node_put(np) in the devm_phy_create() error path drops it twice. Drop the redundant of_node_put() and let the scoped cleanup handle it.
