Multiple platforms stopped booting in next-20150609 as discovered by
kernelci.org[1], and was bisected down to commit b6d2233f2916
(of/platform: Use platform_device interface).

I'll leave you guys to sort out whether that patch or the whole series
should be reverted, but I can confirm that reverting that patch on top
of next-20150609 gets things booting again.
