From bbde14682eba21d86f5f3d6fe2d371b1f97f1e61 Mon Sep 17 00:00:00 2001 From: Miaoqian Lin linmq006@gmail.com Date: Tue, 28 Oct 2025 11:16:20 +0800 Subject: [PATCH] pmdomain: imx: Fix reference count leak in imx_gpc_remove

of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when not needed anymore. Add the missing of_node_put() to avoid refcount leak.
