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 ofnodeput() 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 offindmatchingnode().
