I applied this with the intent of sending a PR to Stephen, but lkp
reported some problems during randconfigs:
https://lore.kernel.org/oe-kbuild-all/202605220724.j4ZeM3KI-lkp@intel.com/
These showed up on microblaze, but I think as they're all from sparse
you should be able to see them on riscv too.

Should all be pretty easy to fix, send a patch and I will squash them
in.

Cheers,
Conor.
