I guess the solution is to replace the include asm/io.h by linux/io.h as Axel Lin did for some other driver in this patch series. @Damien: Can you please do a patch as I suggested and preferable also recheck the other drivers you touched? And it probably would have been a good idea to mention that you didn't compile-test it. I do some compile tests before pushing my branch but that is far from complete due to arch and platform specific drivers.
