I am thinking also on another way of solving this huge-patch problem: 1. Mark all drivers broken (CONFIG_BROKEN). 2. Introduce change in power_supply_register() API. Broken drivers will fail to build. 3. Convert broken drivers to new API incrementally (one driver per patch) marking them also non-broken. This would be much easier to review but also this would break build-bisectability for drivers and some platforms using them (like OLPC, compal-laptop, ACPI). In case of important platforms (like ACPI) I could do the old-way: change the driver along with API change. What do you think about this? I pushed the patchset here: https://git.linaro.org/people/marek.szyprowski/linux-srpol.git/shortlog= /refs/heads/v3.19-next-power-supply-core-ownership (actually this is v4: added acks/reviews and minor issue fixed; merge window has opened so I'll wait with sending this to LKML).
