Type: advisorySources: OSV

In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: Fix refcount leak in ti_dra7_xbar_route_allocate of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not needed anymore. Add missing of_node_put() in to fix this.
