    Use INIT_WORK to initialize struct work and don't initialize a
    struct work partial by explicitly initializing its private structures.
    Fixes the following lockdep bug because no key was assigned:
    
    INFO: trying to register non-static key.
    the code is fine but needs lockdep annotation.
    turning off the locking correctness validator.
