The regulator code is rather foreign to me, but I think I figured out the expectations on the names last night when looking at a similar patch here: http://www.spinics.net/lists/arm-kernel/msg163418.html I'll fix these two patches up, but next time I'll just report the regulator regressions and let the sub-system maintainer or the platform maintainer sort them out.
