From 5d1ca138026ed133f3d11fe0785de82bdee3c648 Mon Sep 17 00:00:00 2001 From: Xiongfeng Wang Date: Wed, 16 Mar 2022 09:19:38 +0100 Subject: media: amphion: Add missing of_node_put() in vpu_core_parse_dt() of_parse_phandle() will increment the refcount of the returned device_node. Calling of_node_put() to avoid the refcount leak.
