Hmm, I did miss reading this. Thanks for pointing out.

Well, arch does matter here. LLCC driver depends on ARCH_QCOM ||
COMPILE_TEST. In the case of ARCH_QCOM, the REGMAP_MMIO is implicitly
selected and you won't see the error with built-in or as a module.

Only if you unselect ARCH_QCOM and use x86_64 (or any other arch) with
COMPILE_TEST, then you'll see the error with both built-in and module.
