From 18e199a5541aad6dc5cf51bc3f712247b2d17894 Mon Sep 17 00:00:00 2001 From: Miaoqian Lin Date: Mon, 4 Apr 2022 08:52:32 +0000 Subject: [PATCH] HSI: omap_ssi: Fix refcount leak in ssi_probe [ Upstream commit 9a2ea132df860177b33c9fd421b26c4e9a0a9396 ] When returning or breaking early from a for_each_available_child_of_node() loop, we need to explicitly call of_node_put() on the child node to possibly release the node.
