I know. But Linux is bigger than U-Boot, and I think we should be able
to fix the few isolated places that throw such warnings.

Agreed, and that's why I want to see this fixed.

I did not look into this yet - there was some discussion about a
malloc replacement, but it faded away without visible result.

I cannot do everything myself, but I can oppose changes that are IMO
to the worse.

Best regards,
