Subject: [PATCH 5.14 062/849] net: mscc: ocelot: Add of_node_put() before goto

From: Wan Jiabing <wanjiabing@...o.com>

[ Upstream commit d1a7b9e4696584ce05c12567762c18a866837a85 ]

Fix following coccicheck warning:
./drivers/net/ethernet/mscc/ocelot_vsc7514.c:946:1-33: WARNING: Function
for_each_available_child_of_node should have of_node_put() before goto.

Early exits from for_each_available_child_of_node should decrement the
node reference counter.
