[PATCH 5.15 038/110] net: marvell: prestera: Add missing of_node_put() in prestera_switch_set_base_mac_addr

[Greg Kroah-Hartman]

From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit c9ffa3e2bc451816ce0295e40063514fabf2bd36 ]

This node pointer is returned by of_find_compatible_node() with
refcount incremented. Calling of_node_put() to aovid the refcount leak.

Fixes: 501ef3066c89 ("net: marvell: prestera: Add driver for Prestera family ASIC devices")
