Subject: [PATCH] phy: renesas: rcar-gen2: Fix double of_node_put on phy creation failure
Date: Mon, 03 Aug 2026 20:43:24 +0800	[thread overview]
Message-ID: <20260803-rcar-gen2-v1-1-9aa35c36d7d7@gmail.com> (raw)

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")
