[PATCH] net: ethernet: ti: davinci_mdio: Drop commas after match table sentinels

[Geert Uytterhoeven]

It does not make sense to have a comma after a sentinel, as any new
elements must be added before the sentinel.

While I agree with it, this seems to require a 'cleanup-series' rather than 
an individual patch, given the following statistics:

As of [0], running
	git grep "sentinel.*}" drivers/net/ | wc -l
gives
	84
and looking for the ones that terminate in a comma by running
	git grep "sentinel.*}," drivers/net/ | wc -l
gives
	38

So there are '37' other instances (apart from davinci_mdio.c) in
drivers/net alone that require a cleanup.

Looking at Linux overall by running
	git grep "sentinel.*}," | wc -l
gives
	396

Since this isn't a functional change, I am not sure why a specific change 
is required in davinci_mdio.c, unless you plan to cleanup the remaining 
'395' occurrences in the remaining code as well. I am not against the 
patch, but the reason for picking just davinci_mdio.c for cleanup isn't 
clear to me based on the commit message.

I have posted the following series to cleanup all networking drivers 
(excluding davinci_mdio.c since that is done by your patch) at:
https://lore.kernel.org/r/20260904043724.2955444-1-s-vadapalli@ti.com/

I know. Over the past few years, I fixed several of them I encountered,
but never got to fixing all of them. After rc1, I flushed a few patches
that could be sent independently, so there it was!

Happy to see my single patch triggered your great response!

Thank you for providing the context for the current patch.

Bummer. I have added a check to my checkpatch wrapper script,
so hopefully this was the last time I made that mistake ;-)
