After a discussion with Bjorn, it appears that he had already solved 
this issue with the following patch: 
https://lore.kernel.org/linux-riscv/20240927131355.350918-1-bjorn@kernel.org/ 
which we find cleaner. I have just tested his, and it indeed fixes the 
build error.

Unless you have any objection, we'll try to make Bjorn's patch into 
6.12-rc7 instead of yours.

Thanks,

Alex
