Subject: [PATCH AUTOSEL 5.14 07/18] net: sparx5: Add of_node_put() before goto

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

[ Upstream commit d9fd7e9fccfac466fb528a783f2fc76f2982604c ]

Fix following coccicheck warning:
./drivers/net/ethernet/microchip/sparx5/s4parx5_main.c:723:1-33: 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.
