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

Pull ARM SoC non-critical bug fixes from Arnd Bergmann:
 "These are bug fixes for harmless problems that were not important
  enough to get fixed in 3.17.  The majority of these are OMAP specific,
  but there are also a couple for Marvell mvebu, cns3xxx, and others, as
  well as some updates for the MAINTAINERS file.

  In particular, Robert Jarzmik and Daniel Mack now volunteered to help
  out maintaining the PXA platform, Krzysztof Halasa took over the
  cns3xxx platform, Carlo Caione is the maintainer for the new Amlogic
  meson platform, and Matthias Brugger is now listed for the mediatek
  platform he recently contributed"
