    firewire: addendum to address handler RCU conversion · 4d50c443

    Follow up on commit c285f6ff6787 "firewire: remove global lock around
    address handlers, convert to RCU":
      - address_handler_lock no longer serializes the address handler, only
        its function to serialize updates to the list of handlers remains.
        Rename the lock to address_handler_list_lock.
      - Callers of fw_core_remove_address_handler() must be able to sleep.
        Comment on this in the API documentation.
      - The counterpart fw_core_add_address_handler() is by nature something
        which is used in process context.  Replace spin_lock_bh() by
        spin_lock() in fw_core_add_address_handler() and in
        fw_core_remove_address_handler(), and document that process context
        is now required for fw_core_add_address_handler().
      - Extend the documentation of fw_address_callback_t.
