Right here.

What compiler version is this?

Compiler is sh4-linux-gnu-gcc (Debian 6.1.1-9) 6.1.1 20160705.

include/asm-generic/io.h conditionally defines iounmap() to be an
empty inline function, which may explain the warning on sh4.

General speaking, it's a false warning. The solution could be to teach
the robot to ignore such 'unused variable' warnings in non-x86 archs.

I think we should change the iounmap stub macro into an inline function.
Does this only happen on sh or other architectures too?

I certainly wouldn't want the warning to be ignored on ARM, or in
general on all architectures other than x86.
