[PATCH 4.9 070/118] cpufreq: tegra124: add missing of_node_put()

From: Greg Kroah-Hartman
Date: Fri Mar 22 2019 - 09:01:24 EST


4.9-stable review patch. If anyone has any objections, please let me know.

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

From: Yangtao Li <tiny.windzz@xxxxxxxxx>

commit 446fae2bb5395f3028d8e3aae1508737e5a72ea1 upstream.

of_cpu_device_node_get() will increase the refcount of device_node,
it is necessary to call of_node_put() at the end to release the
refcount.
