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

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

   - MAINTAINERS updates to add a list for brcmstb and fix a typo
   - A handful of fixes for OMAP 81xx, a recently resurrected platform
     so these can't be considered real regressions and thus got queued.
   - A couple of other small fixes for scoop, sa1100 and davinci"

* tag 'armsoc-fixes-nc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
  ARM: OMAP2+: Fix randconfig build warning for dm814_pllss_data
  ARM: sa1100/simpad: Be sure to clamp return value
  ARM: scoop: Be sure to clamp return value
