From bbdfb7d4f036118d36415a2575efa6f5246505ae Mon Sep 17 00:00:00 2001 From: Peng Wu Date: Fri, 29 Apr 2022 01:03:56 +0200 Subject: [PATCH] ARM: versatile: Add missing of_node_put in dcscb_init [ Upstream commit 23b44f9c649bbef10b45fa33080cd8b4166800ae ] The device_node pointer is returned by of_find_compatible_node with refcount incremented. We should use of_node_put() to avoid the refcount leak.
