framework itself is small enough, just make it a boolean option and avoid the problem entirely. The actual power supply sub drivers can remain modular of course.
We can just do select POWER_SUPPLY.
Well, select'ing otherwise user configurable options was still frowned on last we discussed that... and it makes the whole inline stubs in power_supply.h totally pointless :-)
Yes it reduces the option range for some stupid corner case but really I don't care, removing features from the kernel that a driver depends on is just leading to insane state combination and QA problems.
Well, the power supply stuff only works if you have a backend for it, which not all platforms are, and it's fairly safe to assume AC whenever it's not actually supported.
(Talking of which, we should be able to do a PowerBook backend reasonably easily).
I don't care which solution you guys end up choosing though, just fix it :-)
Cheers, Ben.
