[PATCH] phy: renesas: rcar-gen2: Fix double of_node_put on phy creation failure

Posted by Felix Gu 1 month, 4 weeks ago

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.

Fixes: b64b32791fb5 ("phy: renesas: rcar-gen2: Simplify with scoped for each OF child loop")
