Summary
soc: bcm: brcmstb: pm: pm-arm: Fix refcount leak in brcmstb_pm_probe
Details

In the Linux kernel, the following vulnerability has been resolved:

soc: bcm: brcmstb: pm: pm-arm: Fix refcount leak in brcmstbpmprobe

offindmatchingnode() returns a node pointer with refcount incremented, we should use ofnodeput() on it when not need anymore. Add missing ofnode_put() to avoid refcount leak.

In brcmstbinitsram, it pass dn to ofaddresstoresource(), ofaddresstoresource() will call offinddevicebynode() to take reference, so we should release the reference returned by offindmatching_node().
