[PATCH 4.14 03/37] power/reset: arm-versatile: Fix refcount leak in versatile_reboot_probe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit 80192eff64eee9b3bc0594a47381937b94b9d65a ]

of_find_matching_node_and_match() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Fixes: 0e545f57b708 ("power: reset: driver for the Versatile syscon reboot")
