    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.

    sgtl5000 uses regulator interfaces, so make selecting it depend
