I'm very tempted to say won't fix on this at least not in the IIO code.
The issue I think is the stub for iounmap on sh with no MMU not using the argument because
it's
defined as a while loop rather than as an empty static inline function which is what
we'd
get it it wasn't defined at all (AFAICT).
If anyone wants to take this on, my guess is drop
https://elixir.bootlin.com/linux/latest/source/arch/sh/include/asm/io.h#L274
and see if everything still works and the warning goes away.
+CC linux-sh for inputs.
Thanks,
Jonathan
