commit bae95c5aee1f67da6608ceaebfb744d900e5ffbf
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I60PLB

--------------------------------

[ Upstream commit 0a034d93 ]

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
