Subject: [PATCH 4.19 25/88] phy: samsung: Fix missing of_node_put() in exynos_sata_phy_probe

From: Miaoqian Lin <linmq006@...il.com>

[ Upstream commit 388ec8f079f2f20d5cd183c3bc6f33cbc3ffd3ef ]

The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.

Fixes: bcff4cba41bc ("PHY: Exynos: Add Exynos5250 SATA PHY driver")
