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

Pull ARM SoC non-cricitical bug fixes from Arnd Bergmann:
 "These are various bug fixes that were not considered important enough
  for merging into 3.10.

  The majority of the ARM fixes are for the OMAP and at91 platforms, and
  there is another set of bug fixes for device drivers that resolve
  'randconfig' build errors and that the subsystem maintainers either
  did not pick up or preferred to get merged through the arm-soc tree."
