With CONFIG_TI_K3_AM65_CPSW_NUSS=y and CONFIG_TI_ICSSG_PRUETH=m,
k3-cppi-desc-pool.o is linked to a module and also to vmlinux even though
the expected CFLAGS are different between builtins and modules.
The build system is complaining about the following:
k3-cppi-desc-pool.o is added to multiple modules: icssg-prueth
ti-am65-cpsw-nuss
Introduce the new module, k3-cppi-desc-pool, to provide the common
functions to ti-am65-cpsw-nuss and icssg-prueth.

I submitted a different patch for this a while ago:
https://lore.kernel.org/lkml/[email protected]/
I think I never sent a v2 of that, but I still have a
working version in my local tree. I've replaced my version
with yours for testing now, to see if you still need something
beyond that.

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.

I also fixed a bunch of these in the ethernet/ti/ folder a year ago[0],
you can take a look. I never made it to the upstream branches since I
took a rest from my home Linux projects and never got back to them yet :P

Given that you target the -net tree, please include a suitable fixes

Right, I can resend my patch (or Alexander Lobakin can rebase his version)
after yours makes it in. Note that your patch introduces a warning about
a missing license and description for the new module, so you should
probably include this hunk:
