Subject: [PATCH] irqchip/alpine-msi: Fix refcount leak in alpine_msix_init_domains
Date: Mon,  2 Jan 2023 12:28:10 +0400	[thread overview]
Message-ID: <20230102082811.3947760-1-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: e6b78f2c3e14 ("irqchip: Add the Alpine MSIX interrupt controller")
