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

Pull ARM SoC fixes and straggler patches from Olof Johansson:
 "A collection of fixes for fall out from 3.10 merge window, some build
  fixes and warning cleanups and a small handful of patches that were
  small and contained and made sense to still include in 3.10 (some of
  these have also been in -next since the merge window opened).

  Largest continous series is for OMAP, but there's a handful for other
  platforms.

  For i.MX, one of the patches are framebuffer fixups due to fallout
  during the merge window, and the other removes some stale and broken
  code."
