regmap

Pull a single regmap fix from Mark Brown:
 "A simple bug that's been lurking for a while but not terribly visible
  since a high proportion of chips have no register 0 so the normal
  failure is that we end up doing a bit of extra I/O."

* tag 'regmap-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
  regmap: rbtree: Fix register default look-up in sync
