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

Pull non-critical ARM SoC bug fixes from Arnd Bergmann:
 "Bug fixes that did not make it into v3.8, mostly because they were not
  considered important enough, and in some cases because bugs only show
  up in combination with other patches destined for 3.9.  This includes
  a few larger patches for GPIO on the Marvell PXA platform and a lot of
  Samsung specific bug fixes, as well as a series from Arnd to fix older
  build warnings."
