Hm. Actually, yesterday I applied it to battery-2.6 with assumption
that mfd part will get into mainline in 2.6.27.

Since Kconfig specify that driver depends on MFD_TC6393XB, maximum we'd
get for now is Kconfig warning wrt unknown symbol, but nothing could
select it, thus can't break the build (we have few examples of such
non-selectable drivers even in Linus' tree. For example
drivers/net/cpmac.c: there is no such thing as CONFIG_AR7 -- it is still
in openwrt tree).

But I can git --reset, should I?

I did review this patch, and did mention exactly the same, plus
some other stuff:
http://lkml.org/lkml/2008/6/23/17

Dmitry posted fixed version that I applied:
http://lkml.org/lkml/2008/6/24/266

So, in case this goes through -mm, you'd probably want the fixed version.
