Ok, thanks for the answer.

In any case you should split that series up in per-driver patches. Please try to
make incremental patches, fixing one kconfig/export after the other. The last
patch should be the mt6765 driver being build as a module.

Also fix the commit message saying that you prepare to be able to build pinctrl
drivers as modules or something like this. Only the last patch should mention
mt6765.

Regards,
Matthias
