Subject: soc: bcm: brcmstb: pm: pm-arm: Fix refcount leak in brcmstb_pm_probe
From: Miaoqian Lin <linmq006@xxxxxxxxx>
commit 37d838de369b07b596c19ff3662bf0293fdb09ee upstream.
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
In brcmstb_init_sram, it pass dn to of_address_to_resource(),
of_address_to_resource() will call of_find_device_by_node() to take
reference, so we should release the reference returned by
of_find_matching_node().
