Subject: [PATCH] ARM: tegra: Fix refcount leak in tegra114_gic_cpu_pm_registration
Date: Mon, 23 May 2022 19:20:36 +0400 [thread overview]
Message-ID: <20220523152037.16078-1-linmq006@gmail.com> (raw)
of_find_matching_node() 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: 7e8b15dbc392 ("ARM: tegra114: Reprogram GIC CPU interface to bypass IRQ on CPU PM entry")
