Subject: [PATCH 26/32] net/dsa/hirschmann: Add missing of_node_get() in
 hellcreek_led_setup()
Git-commit: 16d584d2fc8f4ea36203af45a76becd7093586f1
References: git-fixes
Patch-mainline: v5.19-rc5

of_find_node_by_name() will decrease the refcount of its first arg and
we need a of_node_get() to keep refcount balance.

Fixes: 7d9ee2e8ff15 ("net: dsa: hellcreek: Add PTP status LEDs")
