    net: ipa: terminate message handler arrays · 3a9ef3e1
    Alex Elder authored
    When a QMI handle is initialized, an array of message handler
    structures is provided, defining how any received message should
    be handled based on its type and message ID.  The QMI core code
    traverses this array when a message arrives and calls the function
    associated with the (type, msg_id) found in the array.
    
    The array is supposed to be terminated with an empty (all zero)
    entry though.  Without it, an unsupported message will cause
    the QMI core code to go past the end of the array.
    
    Fix this bug, by properly terminating the message handler arrays
    provided when QMI handles are set up by the IPA driver.
