From b8475cbee5ab2eac05f9cd5dbcc94c453d3cbf10 Mon Sep 17 00:00:00 2001 From: Tyrel Datwyler Date: Mon, 17 Apr 2017 20:29:17 -0400 Subject: of: fix "/cpus" reference leak in of_numa_parse_cpu_nodes() The call to of_find_node_by_path("/cpus") returns the cpus device_node with its reference count incremented. There is no matching of_node_put() call in of_numa_parse_cpu_nodes() which results in a leaked reference to the "/cpus" node. This patch adds an of_node_put() to release the reference. fixes: 298535c00a2c ("of, numa: Add NUMA of binding implementation.")
