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

Pull ARM SoC non-urgent fixes from Arnd Bergmann:
 "As usual, we queue up a few fixes that don't seem urgent enough to go
  in through -rc.

   - a number of randconfig warning fixes from Arnd
   - various small fixes for OMAP
   - one somewhat larger patch to restore the OMAP3 cpuidle tuning that
     was lost in a cleanup
   - a small regression fix for cns3xxx PCI"
