Subject: [PATCH] irqchip/irq-mvebu-gicp: Fix refcount leak in mvebu_gicp_probe
Date: Mon, 2 Jan 2023 12:42:08 +0400 [thread overview]
Message-ID: <20230102084208.3951758-1-linmq006@gmail.com> (raw)
of_irq_find_parent() returns a node pointer with refcount incremented,
We should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak.
Fixes: a68a63cb4dfc ("irqchip/irq-mvebu-gicp: Add new driver for Marvell GICP")
