patch 8 also has a warning I can't figure out.

But here (patch 9) it's quite clear:

drivers/net/ethernet/intel/ice/ice_xsk.c:414: warning: Excess function parameter 'alloc' description in 'ice_alloc_rx_bufs_zc'
drivers/net/ethernet/intel/ice/ice_xsk.c:480: warning: Excess function parameter 'xdp' description in 'ice_construct_skb_zc'
