Subject: [PATCH] meson-mx-socinfo: Fix refcount leak in meson_mx_socinfo_init
Date: Tue, 24 May 2022 10:57:29 +0400 [thread overview]
Message-ID: <20220524065729.33689-1-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: 5e68c0fc8df8 ("soc: amlogic: Add Meson6/Meson8/Meson8b/Meson8m2 SoC Information driver")
