You could directly put it in your next tree. If you need me to do
that, please don't hesitate to let me know.

I don't currently plan to send a pull request for the warning
fixes, please just merge it through your own tree for 6.5 or
6.6.
I'd like to enable a few warning options (-Wextra, -Wrestrict,
-Wmissing-prototypes, ...) in the Kbuild for 6.6, but the Makefile
changes will probably go through the Kbuild tree or linux-mm,
and the fixes for existing warnings can just take their normal way.

I just checked my log files again and I now see that there
are actually a number of -Wmissing-prototype warnings as well:

I missed these as I was first looking at everything except
-Wmissing-prototypes that I want to enable. Can you perhaps
help out and create a fix for these yourself?

Okay, I would put it in my tree.
