Subject: [PATCH 5.15 89/98] drivers: cpufreq: Add missing of_node_put() in qoriq-cpufreq.c

From: Liang He <windhl@....com>

[ Upstream commit 4ff5a9b6d95f3524bf6d27147df497eb21968300 ]

In qoriq_cpufreq_probe(), of_find_matching_node() will return a
node pointer with refcount incremented. We should use of_node_put()
when it is not used anymore.

Fixes: 157f527639da ("cpufreq: qoriq: convert to a platform driver")
