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

Pull ARM SoC fixes from Olof Johansson:
 "A small batch of fixes that have trickled in over the last week of the
  merge window.

  Also included are few small devicetree updates for sunxi, since it
  enables me to use one of their newer boards (cubieboard2) for
  additional test coverage.  The support for that SoC is new for 3.12,
  so there's no exposure to new regressions due to it"
