Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC fixes from Arnd Bergmann:
 "A first set of bug fixes that didn't make it for the merge window, and
  two Kconfig cleanups that still make sense at this point.

  Unfortunately, one of the two cleanups caused an unintended change in
  the original version, so we had to revert one part of it and do some
  more testing to ensure the rest is really fine.  There was also a
  last-minute rebase of the patches to remove another bad commit"
