Subject: Re: [PATCH 1/4] platform: x86: intel_cht_int33fe: Fix dependencies

Hi,

Hmm, the dependency is pure run-time, with this Kconfig
change if a user now decides to builtin the intel_cht_int33fe
driver, the bq24190 driver must also be builtin, I'm not sure
if that is a good thing.

Regards,

Hans
