I have issues applying the patch:

    KEYS: trusted: tee: Refactor register SHM usage

    The OP-TEE driver using the old SMC based ABI permits overlapping shared
    buffers, but with the new FF-A based ABI each physical page may only
    be registered once.

    As the key and blob buffer are allocated adjancently, there is no need
    for redundant register shared memory invocation. Also, it is incompatibile
    with FF-A based ABI limitation. So refactor register shared memory
    implementation to use only single invocation to register both key and blob
    buffers.
