Subject: [PATCH AUTOSEL 5.18 39/53] arch: mips: generic: Add missing of_node_put() in board-ranchu.c

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

[ Upstream commit 4becf6417bbdc293734a590fe4ed38437bbcea2c ]

In ranchu_measure_hpt_freq(), of_find_compatible_node() will return
a node pointer with refcount incremented. We should use of_put_node()
when it is not used anymore.
