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

Pull ARM SoC Non-critical bug fixes from Olof Johansson:
 "Simple bug fixes that were not considered important enough for
  inclusion into 3.7, especially those that arrived late during the
  merge window.

  There's also a MAINTAINERS update for the Renesas platforms in here,
  marking Simon Horman as a maintainer and changing the git url to his
  tree."
