[PATCH] drivers: soc: bcm: brcmstb: Add missing of_node_put() in biuctrl.c

From: Liang He
Date: Wed Jun 15 2022 - 10:04:12 EST


In brcmstb_biuctrl_init(), of_find_compatible_node() will return a
node pointer with refcount incremented. We should use of_node_put()
in each fail path or when it is not used anymore.
