has been pushed upstream - although the build breakage was reported against 
linux-next two weeks ago, with fix provided, in this lkml thread:

  [PATCH -next] soc: sgtl5000 uses regulator interfaces

Please do not push known-broken code upstream.

Randy's fix below resolved the bug for me.

Thanks,

Subject: [PATCH] soc: Sgtl5000 uses regulator interfaces

sgtl5000 uses regulator interfaces, so make selecting it depend
on REGULATOR.
