Description OSIDB Bzimport 2025-02-26 03:08:11 UTC 
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.
