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.
