Hi,
With LLVM 21.1.8, I am seeing in an `allmodconfig` for next-20260121:

It seems that indeed the variables are duplicated -- something seems
off with commit

Thanks!

I have sent
https://lore.kernel.org/20260114-panel-ilitek-ili9882t-fix-override-init-v1-1-1d69a2b096df@kernel.org/
for this, it just needs verification and application.
Cheers,
Nathan
