Summary
In the Linux kernel, the following vulnerability has been resolved: mips: cavium-octeon: Fix missing of_node_put() in octeon2_usb_clocks_start We should call of_node_put() for the reference 'uctl_node' returned by of_get_parent() which will increase the refcount. Otherwise, there will be a refcount leak bug.
