pmdomain: imx: Fix reference count leak in imx_gpc_remove

Yuuoniy · gregkh · commit 378e6136b8c0 · 2025-12-01T11:41:53.000+01:00
[ Upstream commit bbde146 ] 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.
