It looks like you need to disable "module" in the corresponding Kconfig.

Do you want to add another patch to make it compilable as a module? or
do you want to make it "tristate" --> "bool"?

If you want the latter, I can do it for you before I send a pull request.

Please refer to the following:



mzx@kohaku:/home/kernel.org/devfreq$ make ARCH=arm modules
  CHK     include/config/kernel.release
  CHK     include/generated/uapi/linux/version.h
  CHK     include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
