Description
In the Linux kernel, the following vulnerability has been resolved: mips: cdmm: Fix refcount leak in mips_cdmm_phys_base The of_find_compatible_node() function returns a node pointer with refcount incremented, We should use of_node_put() on it when done Add the missing of_node_put() to release the refcount.
