I see your patch addresses different modules. My patch introduces a new
module for k3-cppi-desc-pool which is used by both am65-cpsw-nuss and
icssg-prueth driver. Where as your patch addresses modules common across
different cpsw drivers (davinci-emac, cpsw, cpsw-switchdev, netcp,
netcp_ethss and am65-cpsw-nuss). So I think that both these patches are
addressing differet warnings.
