Summary
soc: qcom: ocmem: Fix refcount leak in of_get_ocmem
Details

In the Linux kernel, the following vulnerability has been resolved:

soc: qcom: ocmem: Fix refcount leak in ofgetocmem

ofparsephandle() returns a node pointer with refcount incremented, we should use ofnodeput() on it when not need anymore. Add missing ofnodeput() to avoid refcount leak. ofnodeput() will check NULL pointer.
